A particle in a two-dimensional square well of width a with a weak potential in the form of a delta function: Vx, y) = Voa 28(x – a/4)S(y - al4). Write down the unperturbed energy and wavefunction, and use perturbation techniques to find: a. The first order correction to the ground state energy b. The first three non-zero terms in the second order correction to the ground state energy A particle in a two-dimensional square well of width a with a weak potential in the form of a delta function: Vx, y) = Voa 28(x – a/4)S(y - al4).
