Abstract
An elementary treatment of the Dirac equation in the presence of a three-dimensional spherically symmetric δ(r - r0 )-potential is presented. We show how to handle the matching conditions in configuration space, and discuss the occurrence of supercritical effects. † On leave of absence from Pontificia Universidad Católica del Perú, Lima, Perú.
