Its a problem from a foreign book. It sounded simple to me but I am confused now.
If V(x), a potential energy function, is known to be an even function, what can you say about wave function for any stationary state? What shall be the expectation value of x for any stationary state ?
The Attempt at a Solution
I grabbed a book by Griffith from my library and figured that if V(x) is even, the time independent wave function can be taken to be either even or odd. I know that expectation value of x for a stationary state has to be 0. But can some help me see this with the standpoint of V(x) being even ?
thanks in advance
