Find the energy eigenvalues of a particle confined by a potential of the following form: +oo, V(r)= { }mu22, if 2 0. if r0 < Sketch the potential so that you have a visual picture of it. Hint: Use the fact that we already know the energy eigenvalues and eigenfunctions of the Schrödi- inger equation in the quadratic potential and impose an additional requirement to the wave func- tions that follows from V(r) = 0. o for
