The spinless relativistic Woods–Saxon problem

Abstract

Motivated by the observation of a recent renewal of rather strong interest in the description of bound states by (semi)relativistic equations of motion, we revisit, for the example of the Woods–Saxon interactions, the eigenvalue problem posed by the spinless Salpeter equation and recall various elementary knowledge, considerations and techniques that practitioners seeking solutions to this specific reduction of the Bethe–Salpeter equation may find helpful.
