## Details

Energies are in units with , and the mass of the particle is 1/2. The eigenenergies of the unperturbed potential (the infinite square well of width 1) are . The case with and is the "V-bottom" potential, which is studied by perturbation methods in Appendix J of [1]. The case with leads to the so-called infinite tilted well. Its exact solution is given in [2].
