Abstract
The production of (e+, e-) pairs is calculated in a nonperturbative ap proach for the model situation of a one-dimensional square well with a depth varying with time. Detailed energy distributions for the averag e particle number of electrons and positrons are obtained. In contrast to other (almost) exactly solvable models for pair-creation bound-sta te effects can be included. Situations with both undercritical and ove rcritical potentials are considered.
