Vodikov atom v homogenem magnetnem polju <math>\mathbf{B}_{0}=B_{0}\mathbf{e}_{z}</math> je ob <math>t=-\infty</math> v osnovnem stanju (ker je magnetni moment elektrona <math>\boldsymbol{\mu}=-2\frac{\mu_{B}}{\hbar}\mathbf{S}</math> obrnjen nasprotno kot njegov spin, je v osnovnem stanju <math>S_{z}\left|\psi\right\rangle =-\frac{\hbar}{2}\left|\psi\right\rangle </math>). Nato vklopimo dodatno šibko magnetno polje <math>\mathbf{B}_{1}\left(t\right)=B_{1}e^{\frac{t}{\tau}}\mathbf{e}_{x}</math>.<br />
#Kolikšna je verjetnost, da pri meritvi <math>S_{z}</math> ob <math>t=0</math> izmerimo vrednost <math>\frac{\hbar}{2}</math>? Računaj v prvem redu perturbacije!<br />
