Abstract
After a review of the results obtained in the quantum square well problem in the last six decades, Garrett's approach is
reformulated in a consistent way, and Barker's solution is deduced using a simple method. A new analytic approximation for
the roots of the transcendental equations for the energy eigenvalues is proposed, with applications to the study of quantum
wells and resonant cavities..
