		<summary type="html">&lt;p&gt;Die Seite wurde neu angelegt: „{{Scripthinweis|Quantenmechanik|4|2}} Die potenzielle Energie des magnetischen Moments des Elektronen- Spins&amp;lt;math&amp;gt;\bar{\mu }&amp;lt;/math&amp;gt;  im äußeren Magnetfeld &amp;lt;math…“&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Neue Seite&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Scripthinweis|Quantenmechanik|4|2}}&lt;br /&gt;
Die potenzielle Energie des magnetischen Moments des Elektronen- Spins&amp;lt;math&amp;gt;\bar{\mu }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
im äußeren Magnetfeld &amp;lt;math&amp;gt;\bar{B}=B{{\bar{e}}_{3}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
beträgt:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;V=-\hat{\bar{\mu }}\cdot \bar{B}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
mit &amp;lt;math&amp;gt;\hat{\bar{\mu }}=+g\frac{e}{2{{m}_{0}}}\hat{\bar{S}}=+\frac{e\hbar }{2{{m}_{0}}}\hat{\bar{\sigma }}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
mit g~ 2 und   e&amp;lt;0&lt;br /&gt;
&lt;br /&gt;
Somit:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\hat{V}=-\frac{e\hbar }{2{{m}_{0}}}\hat{\bar{\sigma }}\cdot \bar{B}=-\frac{e\hbar B}{2{{m}_{0}}}{{\hat{\bar{\sigma }}}_{3}}=\hbar {{\omega }_{l}}{{\hat{\bar{\sigma }}}_{3}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Mit der Larmor- Frequenz &amp;lt;math&amp;gt;{{\omega }_{l}}:=\frac{|e|B}{2{{m}_{0}}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Wenn der Spin an keine weitere Variable ankoppelt, so ist &amp;lt;math&amp;gt;\hat{H}=\hat{V}&amp;lt;/math&amp;gt;&lt;br /&gt;
der Hamiltonoperator der Spinvariable ( im Spin- Hilbertraum).&lt;br /&gt;
Die Dynamik eines Spins im Magnetfeld ergibt sich über den Zeitableitungsoperator:&lt;br /&gt;
&amp;lt;math&amp;gt;{{\hat{\bar{\sigma }}}^{\circ }}=\frac{i}{\hbar }\left[ \hat{H},\hat{\bar{\sigma }} \right]=i{{\omega }_{l}}\left[ {{{\hat{\bar{\sigma }}}}_{3}},{{{\hat{\bar{\sigma }}}}_{{}}} \right]&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Berechnung der Erwartungswerte mit &amp;lt;math&amp;gt;\left[ {{{\hat{\bar{\sigma }}}}_{j}},{{{\hat{\bar{\sigma }}}}_{k}} \right]=2i{{\varepsilon }_{jkl}}{{\hat{\bar{\sigma }}}_{l}}&amp;lt;/math&amp;gt;&lt;br /&gt;
:&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{d}{dt}\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle =\frac{i}{\hbar }\left\langle \left[ H,{{{\hat{\bar{\sigma }}}}_{1}} \right] \right\rangle =i{{\omega }_{l}}\left\langle \left[ {{{\hat{\bar{\sigma }}}}_{3}},{{{\hat{\bar{\sigma }}}}_{1}} \right] \right\rangle =-2{{\omega }_{l}}\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \frac{d}{dt}\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle =-2{{\omega }_{l}}\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle  \\&lt;br /&gt;
&amp;amp; \frac{d}{dt}\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle =2{{\omega }_{l}}\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle  \\&lt;br /&gt;
&amp;amp; \frac{d}{dt}\left\langle {{{\hat{\bar{\sigma }}}}_{3}} \right\rangle =0 \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dies läßt sich reduzieren:&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{{{d}^{2}}}{d{{t}^{2}}}\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle +{{\left( 2{{\omega }_{l}} \right)}^{2}}\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle =0&amp;lt;/math&amp;gt;&lt;br /&gt;
Die Dynamik der Spins bildet also einen Oszillator in der x-y- Ebene.&lt;br /&gt;
Die zeitliche Unabhängigkeit der Spin3- Komponente liegt dabei alleine an der Wahl des Koordinatensystems, bzw. der Basis ! Wir haben diese gerade so gewählt, dass die 3- Komponente zeitlich unabhängig wird.&lt;br /&gt;
Die Lösung der Diffgleichung liefert:&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; {{\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle }_{t}}={{\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle }_{0}}\sin \left( 2{{\omega }_{l}}t \right)+{{\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle }_{0}}\cos \left( 2{{\omega }_{l}}t \right) \\&lt;br /&gt;
&amp;amp; {{\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle }_{t}}={{\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle }_{0}}\cos \left( 2{{\omega }_{l}}t \right)-{{\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle }_{0}}\sin \left( 2{{\omega }_{l}}t \right) \\&lt;br /&gt;
&amp;amp; {{\left\langle {{{\hat{\bar{\sigma }}}}_{3}} \right\rangle }_{t}}={{\left\langle {{{\hat{\bar{\sigma }}}}_{3}} \right\rangle }_{0}} \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Die Anfangsbedingungen können ebenfalls durch Wahl des Koordinatensystems ( feste x-y- Ebene) beeinflusst werden.&lt;br /&gt;
Wähle:&lt;br /&gt;
o.B. d.A.:&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle }_{0}}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Wir können uns den Betrag des Erwartungswertes des gesamten Spinvektors ansehen und es zeigt sich :&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left| {{\left\langle {{{\hat{\bar{\sigma }}}}_{{}}} \right\rangle }_{t}} \right|}^{2}}={{\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle }_{t}}^{2}+{{\left\langle {{{\hat{\bar{\sigma }}}}_{2}} \right\rangle }_{t}}^{2}+{{\left\langle {{{\hat{\bar{\sigma }}}}_{3}} \right\rangle }_{t}}^{2}={{\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle }_{0}}^{2}\left[ {{\cos }^{2}}\left( 2{{\omega }_{l}}t \right)+{{\sin }^{2}}\left( 2{{\omega }_{l}}t \right) \right]+{{\left\langle {{{\hat{\bar{\sigma }}}}_{3}} \right\rangle }_{0}}^{2}={{\left\langle {{{\hat{\bar{\sigma }}}}_{1}} \right\rangle }_{0}}^{2}+{{\left\langle {{{\hat{\bar{\sigma }}}}_{3}} \right\rangle }_{0}}^{2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Mit anderen Worten:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left| {{\left\langle {{{\hat{\bar{\sigma }}}}_{{}}} \right\rangle }_{t}} \right|}^{2}}={{\left| {{\left\langle {{{\hat{\bar{\sigma }}}}_{{}}} \right\rangle }_{0}} \right|}^{2}}=const&amp;lt;/math&amp;gt;&lt;br /&gt;
, der Betrag des Spins ändert sich zeitlich nicht !&lt;br /&gt;
&lt;br /&gt;
Der Erwartungswert des Spins präzediert also mit der Frequenz &amp;lt;math&amp;gt;2{{\omega }_{l}}&amp;lt;/math&amp;gt;&lt;br /&gt;
um das Magnetfeld.&lt;br /&gt;
&lt;br /&gt;
====Schrödingergleichung  für die Spinzustände ( Pauli- Gleichungen)====&lt;br /&gt;
&amp;lt;math&amp;gt;\hbar {{\omega }_{l}}{{\hat{\bar{\sigma }}}_{3}}\left| a(t) \right\rangle =i\hbar \frac{\partial }{\partial t}\left| a(t) \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
Achtung ! Nur  Spin- Hamiltonian !&lt;br /&gt;
Dabei muss der Zustand &amp;lt;math&amp;gt;\left| a(t) \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
in der Spinbasis entwickelbar sein:&lt;br /&gt;
&amp;lt;math&amp;gt;\left| a(t) \right\rangle ={{a}_{1}}(t)\left| \uparrow  \right\rangle +{{a}_{2}}(t)\left| \downarrow  \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Matrix- Darstellung:&amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\hbar {{\omega }_{l}}\left( \begin{matrix}&lt;br /&gt;
1 &amp;amp; 0  \\&lt;br /&gt;
0 &amp;amp; -1  \\&lt;br /&gt;
\end{matrix} \right)\left( \begin{matrix}&lt;br /&gt;
{{a}_{1}}(t)  \\&lt;br /&gt;
{{a}_{2}}(t)  \\&lt;br /&gt;
\end{matrix} \right)=i\hbar \frac{\partial }{\partial t}\left( \begin{matrix}&lt;br /&gt;
{{a}_{1}}(t)  \\&lt;br /&gt;
{{a}_{2}}(t)  \\&lt;br /&gt;
\end{matrix} \right)\Leftrightarrow \begin{matrix}&lt;br /&gt;
-i{{\omega }_{l}}{{a}_{1}}={{{\dot{a}}}_{1}}  \\&lt;br /&gt;
i{{\omega }_{l}}{{a}_{2}}={{{\dot{a}}}_{2}}  \\&lt;br /&gt;
\end{matrix}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Die Lösung lautet:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; {{a}_{1}}(t)={{a}_{10}}{{e}^{-i{{\omega }_{l}}t}} \\&lt;br /&gt;
&amp;amp; {{a}_{2}}(t)={{a}_{20}}{{e}^{i{{\omega }_{l}}t}} \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\left| a(t) \right\rangle ={{a}_{10}}{{e}^{-i{{\omega }_{l}}t}}\left| \uparrow  \right\rangle +{{a}_{20}}{{e}^{i{{\omega }_{l}}t}}\left| \downarrow  \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Nebenbemerkung: Hieraus gewinnt man &amp;lt;math&amp;gt;{{\left\langle {{{\hat{\bar{\sigma }}}}_{j}} \right\rangle }_{t}}&amp;lt;/math&amp;gt;&lt;br /&gt;
, also die Spinpräzession wie oben !&lt;br /&gt;
&lt;br /&gt;
===Zustände mit Bahn- und Spinvariablen===&lt;br /&gt;
&lt;br /&gt;
Sei nun &amp;lt;math&amp;gt;\left| nlm{{m}_{s}} \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
ein Zustand, der Bahn- und Spinfreiheitsgrade beschreibt:&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \left| nlm{{m}_{s}} \right\rangle =\left| nlm \right\rangle \left| {{m}_{s}} \right\rangle \in {{H}_{B}}\times {{H}_{S}} \\&lt;br /&gt;
&amp;amp; \left| nlm \right\rangle \in {{H}_{B}} \\&lt;br /&gt;
&amp;amp; \left| {{m}_{s}} \right\rangle \in {{H}_{S}} \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Der Bahnzustand ist Element des Bahn- Hilbertraumes und der Spinzustand Element des Spin- Hilbertraumes. Der Gesamtzustand erfordert einen Raum, der sich als DIREKTES  PRODUKT der beiden Hilberträume zeigt.&lt;br /&gt;
Allgemein gilt für separable oder Produktzustände &amp;lt;math&amp;gt;\left| {{n}_{1}}{{n}_{2}} \right\rangle =\left| {{n}_{1}} \right\rangle \left| {{n}_{2}} \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
( äquivalente Sprechweise):&lt;br /&gt;
&amp;lt;math&amp;gt;\left\langle  {{m}_{1}}{{m}_{2}} \right|\left| {{n}_{1}}{{n}_{2}} \right\rangle =\left\langle  {{m}_{1}}{{m}_{2}} \right|\left| {{n}_{1}} \right\rangle \left\langle  {{m}_{1}}{{m}_{2}} \right|\left| {{n}_{2}} \right\rangle =\left\langle  {{m}_{1}} \right|\left| {{n}_{1}} \right\rangle \left\langle  {{m}_{2}} \right|\left| {{n}_{2}} \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ein beliebiger Zustand kann nach Spin- Basis Zuständen &amp;lt;math&amp;gt;\left| \uparrow  \right\rangle ,\left| \downarrow  \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
zerlegt werden:&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left| \Psi  \right\rangle }_{t}}={{\left| {{\Psi }_{1}} \right\rangle }_{t}}\left| \uparrow  \right\rangle +{{\left| {{\Psi }_{2}} \right\rangle }_{t}}\left| \downarrow  \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
mit&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left| {{\Psi }_{\alpha }} \right\rangle }_{t}}=\int_{{}}^{{}}{{{d}^{3}}r}\left| {\bar{r}} \right\rangle \left\langle  {\bar{r}} \right|{{\left| {{\Psi }_{\alpha }} \right\rangle }_{t}}&amp;lt;/math&amp;gt;&lt;br /&gt;
In der Ortsraum- Basis mit dem Bahn- Zustand  &amp;lt;math&amp;gt;\alpha =1,2&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In der Matrix- Darstellung des Spinraumes ergibt dies:&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left| \Psi  \right\rangle }_{t}}=\left( \begin{matrix}&lt;br /&gt;
{{\left| {{\Psi }_{1}} \right\rangle }_{t}}  \\&lt;br /&gt;
{{\left| {{\Psi }_{2}} \right\rangle }_{t}}  \\&lt;br /&gt;
\end{matrix} \right)=\int_{{}}^{{}}{{{d}^{3}}r}\left| {\bar{r}} \right\rangle \left( \begin{matrix}&lt;br /&gt;
\left\langle  {\bar{r}} \right|{{\left| {{\Psi }_{1}} \right\rangle }_{t}}  \\&lt;br /&gt;
\left\langle  {\bar{r}} \right|{{\left| {{\Psi }_{2}} \right\rangle }_{t}}  \\&lt;br /&gt;
\end{matrix} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Mit&lt;br /&gt;
&amp;lt;math&amp;gt;\left( \begin{matrix}&lt;br /&gt;
{{\left| {{\Psi }_{1}} \right\rangle }_{t}}  \\&lt;br /&gt;
{{\left| {{\Psi }_{2}} \right\rangle }_{t}}  \\&lt;br /&gt;
\end{matrix} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
entsprechend 2 Spinkomponenten, also entsprechend &amp;lt;math&amp;gt;\left| \uparrow  \right\rangle ,\left| \downarrow  \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Die Vollständigkeit der Zustände &amp;lt;math&amp;gt;\left| \bar{r}\uparrow  \right\rangle =\left| {\bar{r}} \right\rangle \left| \uparrow  \right\rangle ,\left| \bar{r}\downarrow  \right\rangle =\left| {\bar{r}} \right\rangle \left| \downarrow  \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
folgt aus:&lt;br /&gt;
&amp;lt;math&amp;gt;\int_{{}}^{{}}{{{d}^{3}}r\left\{ \left| \bar{r}\uparrow  \right\rangle \left\langle  \bar{r}\uparrow  \right|+\left| \bar{r}\downarrow  \right\rangle \left\langle  \bar{r}\downarrow  \right| \right\}}=1\quad \in {{H}_{B}}\times {{H}_{S}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Weiter:&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \left\langle  \bar{r}\uparrow  \right|{{\left| \Psi  \right\rangle }_{t}}=\left\langle  {\bar{r}} \right|{{\left| {{\Psi }_{1}} \right\rangle }_{t}} \\&lt;br /&gt;
&amp;amp; \left\langle  \bar{r}\downarrow  \right|{{\left| \Psi  \right\rangle }_{t}}=\left\langle  {\bar{r}} \right|{{\left| {{\Psi }_{2}} \right\rangle }_{t}} \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
Also die Komponenten von &amp;lt;math&amp;gt;{{\left| \Psi  \right\rangle }_{t}}&amp;lt;/math&amp;gt;&lt;br /&gt;
am Ort &amp;lt;math&amp;gt;\bar{r}&amp;lt;/math&amp;gt;&lt;br /&gt;
, einmal die Komponente mit Spin &amp;lt;math&amp;gt;\uparrow &amp;lt;/math&amp;gt;&lt;br /&gt;
und einmal die Komponente mit Spin &amp;lt;math&amp;gt;\downarrow &amp;lt;/math&amp;gt;&lt;br /&gt;
.  Dabei gilt:&lt;br /&gt;

\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{\hat{H}}_{S}}&amp;lt;/math&amp;gt;&lt;br /&gt;
wirkt dabei nur im Hilbertraum &amp;lt;math&amp;gt;{{H}_{S}}&amp;lt;/math&amp;gt;&lt;br /&gt;

&amp;amp; \alpha =1,2 \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Also haben wir je nach Spinzustand schon 2 Schrödingergleichungen in &amp;lt;math&amp;gt;{{H}_{B}}&amp;lt;/math&amp;gt;&lt;br /&gt;
:&lt;br /&gt;
Es gilt (äquivalente Darstellung):&lt;br /&gt;

PAULI- GLEICHUNG&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Anwendung&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
- einfacher Zeeman- Effekt mit Spin.  1 Elektron im kugelsymmetrischen Potenzial ( Kern (H)oder Atomrumpf(Na)) und homogenen Magnetfeld &amp;lt;math&amp;gt;\bar{B}=B{{\bar{e}}_{3}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\hat{H}={{\hat{H}}_{B}}\times 1+{{H}_{S}}=\left[ \frac{1}{2{{m}_{0}}}{{\left( \bar{p}-e\bar{A} \right)}^{2}}+V(r) \right]\times 1-\frac{\left| e \right|\hbar B}{2{{m}_{0}}}{{\hat{\bar{\sigma }}}_{3}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dabei wird durch &amp;lt;math&amp;gt;{{\hat{H}}_{B}}\times 1&amp;lt;/math&amp;gt;&lt;br /&gt;
der Bahndrehimpuls Hamiltonian durch den Spinraum erweitert.&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \hat{H}={{{\hat{H}}}_{B}}\times 1+{{H}_{S}}=\left[ \frac{1}{2{{m}_{0}}}{{\left( \bar{p}-e\bar{A} \right)}^{2}}+V(r) \right]\times 1-\frac{\left| e \right|\hbar B}{2{{m}_{0}}}{{{\hat{\bar{\sigma }}}}_{3}} \\&lt;br /&gt;
&amp;amp; \hat{H}\cong \left[ \frac{{{{\bar{p}}}^{2}}}{2{{m}_{0}}}+V(r) \right]\times 1-\frac{\left| e \right|B}{2{{m}_{0}}}\left( {{{\hat{L}}}_{3}}\times 1+\hbar {{{\hat{\bar{\sigma }}}}_{3}} \right) \\&lt;br /&gt;
&amp;amp; \frac{{{{\bar{p}}}^{2}}}{2{{m}_{0}}}+V(r)={{H}_{0}} \\&lt;br /&gt;
&amp;amp; {{H}_{0}}\left| nlm \right\rangle ={{E}_{nl}}\left| nlm \right\rangle  \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Wie man sieht bekommt man durch den Korrekturterm &amp;lt;math&amp;gt;\frac{\left| e \right|B}{2{{m}_{0}}}\left( {{{\hat{L}}}_{3}}\times 1+\hbar {{{\hat{\bar{\sigma }}}}_{3}} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
eine Korrektur an die Energie.&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Für B=0 -&amp;gt; Eigenzustände  mit Spin&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&amp;lt;math&amp;gt;\left( {{H}_{0}}\times 1 \right)\left| nlm{{m}_{s}} \right\rangle ={{E}_{nl}}\left| nlm{{m}_{s}} \right\rangle &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Insgesamt &amp;lt;math&amp;gt;2\left( 2l+1 \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
fach entartet. Beim H- Atom: zusätzliche l- Entartung&lt;br /&gt;
&amp;lt;math&amp;gt;B\ne 0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \hat{H}\left| nlm{{m}_{s}} \right\rangle ={{H}_{0}}\left| nlm \right\rangle \left| {{m}_{s}} \right\rangle -\frac{\left| e \right|B}{2{{m}_{0}}}\left\{ \left( {{{\hat{L}}}_{3}}\left| nlm \right\rangle  \right)\left| {{m}_{s}} \right\rangle +\hbar \left( {{{\hat{\bar{\sigma }}}}_{3}}\left| {{m}_{s}} \right\rangle  \right)\left| nlm \right\rangle  \right\} \\&lt;br /&gt;
&amp;amp; {{{\hat{L}}}_{3}}\left| nlm \right\rangle =\hbar m\left| nlm \right\rangle  \\&lt;br /&gt;
&amp;amp; {{{\hat{\bar{\sigma }}}}_{3}}\left| {{m}_{s}} \right\rangle =2{{m}_{S}}\left| {{m}_{s}} \right\rangle  \\&lt;br /&gt;
&amp;amp; {{H}_{0}}\left| nlm \right\rangle \left| {{m}_{s}} \right\rangle -\frac{\left| e \right|B}{2{{m}_{0}}}\left\{ \left( {{{\hat{L}}}_{3}}\left| nlm \right\rangle  \right)\left| {{m}_{s}} \right\rangle +\hbar \left( {{{\hat{\bar{\sigma }}}}_{3}}\left| {{m}_{s}} \right\rangle  \right)\left| nlm \right\rangle  \right\}=\left[ {{E}_{nl}}-\frac{\left| e \right|\hbar B}{2{{m}_{0}}}\left( m+2{{m}_{s}} \right) \right]\left| nlm{{m}_{s}} \right\rangle  \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Das bedeutet:&lt;br /&gt;
teilweise Aufhebung der &amp;lt;math&amp;gt;2(2l+1)&amp;lt;/math&amp;gt;&lt;br /&gt;
- fachen Entartung&lt;br /&gt;
( sogenannter Anomaler Zeemann- Effekt !)&lt;br /&gt;
&amp;lt;math&amp;gt;E={{E}_{nl}}-{{\mu }_{B}}B\left( m+2{{m}_{s}} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dies gilt für PARAMAGNETISCHE Atome mit magnetischem Moment&lt;br /&gt;
&amp;lt;math&amp;gt;{{\mu }_{3}}={{\mu }_{B}}\left( m+2{{m}_{s}} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dabei entspricht&lt;br /&gt;
&amp;lt;math&amp;gt;2&amp;lt;/math&amp;gt;&lt;br /&gt;
vor ms dem gyromagnetischen Verhältnis, kommt also wegen dem Landé- Faktor g=2, auch wenn dieser leicht von 2 verschieden ist ! ( Siehe oben).&lt;br /&gt;
Für dieses Beispiel wird die Energieverschiebung linear zu B am besten in Einheiten von &amp;lt;math&amp;gt;{{\mu }_{B}}&amp;lt;/math&amp;gt;&lt;br /&gt;
angegeben. s und p - Orbital lassen sich folgendermaßen in einem sogenannten Termschema skizzieren ( für den anomalen Zeemann- Effekt ):&lt;br /&gt;
Das heißt: die m- Entartung, die ohne Spin vollständig aufgehoben wurde, ist jetzt nur noch teilweise aufgehoben !&lt;br /&gt;
Da die Aufhebung der Spin- Entartung die Energiezustände wieder so &amp;quot; weiterrückt&amp;quot;, dass vorher getrennte wieder zusammenfallen !&lt;br /&gt;
