Problem 9.3 (a) Find the exact energies and wave functions of the ground and first excited states and specify their degeneracies for the infinite cubic potential well 10 * if0<x<L₂0<y <L,0<:<L, otherwise. Now add the following perturbation to the infinite cubic well: Vol'sx--- (b) Using first-order perturbation theory, calculate the energy of the ground state. (c) Using first-order (degenerate) perturbation theory, calculate the energy of the first ex- cited state.
