  I develop the solution to the problem of an electron confined in a composite
quadratic well subject to a simple, external periodic force. The method of
solution illustrates several of the basic techniques useful in formally solving
the one-dimensional, time-dependent Schrodinger equation. One of the aims of
this exercise is to see how far is it possible to push analytics, before
plowing into numerical methods. I hope this presentation of the problem may
result useful to others seeking to gain additional experience in the details of
solving the time-dependent Schrodinger equation in one space dimension.
