[tex] e^\left(-i V_0 t / \hbar \right) [/tex],

when you add a constant [itex] V_0 [/itex] to the potential energy. And then it asks what effect does this have on the expecation value of a dynamical variable?

Assuming I only have been given the Schrodinger eqn thus far, and there has not been any discussion thus far about solutions for the equation, where do I start? I was thinking about replacing the V in the equation with [itex] V + V_0 [/itex], but I'm not sure how that would lead to getting the phase factor they talk about.

[tex]

i \hbar \left( \frac {\partial \psi}_{\partial t} \right) = - \left( \frac {\hbar^2}_{2m} \right) \left( \frac {\partial^2 \psi}_{\partial x^2} \right) + V \psi + V_0 \psi

[/tex]

Any ideas?
