(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the expectation value of [tex]\hat{H}'[/tex] in the state [tex]\psi(x,t=0)[/tex].

[tex]\hat{H}'=k(\hat{x}\hat{p}+\hat{p}\hat{x})[/tex]

[tex]\psi(x,t=0)=A(\sqrt{3}i\varphi_{1}(x)+\varphi_{3}(x))[/tex],

where [itex]A=\frac{1}{2}[/itex]

2. Relevant equations

3. The attempt at a solution

I know it's found by:

[tex]\left\langle\psi,\hat{H}'\psi\right\rangle[/tex],

but it's been so long since I calculated this, so I'm not quite sure how to tackle/calculate it to be honest.

So I hope you might be able to give me some pointers.

Regards.
