Homework Help: Particle in a box - perturbation theory

  1. Apr 17, 2009 #1
    1. The problem statement, all variables and given/known data

    Find the ground state energy of a particle restricted to move in one dimension subject to the potential in the attachement using perturbation theory.

    2. Relevant equations
    Yo = (2/a)1/2 sin(nπx/a)

    3. The attempt at a solution

    I'm not sure how to account for the potential since there are two wells.

    My setup right now using braket notation is E = 2<Y|Y> + <Y|Vo|Y> where Y is the wavefunction Yo = (2/a)1/2 sin(nπx/a)

    Can I get some feedback as to if I am headed in the right direction or how to get there if I am not?

    Thank you.
