Semiclassical theory of positron emission in transient supercritical atoms

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Within the semiclassical approximation (WKB) we present an estimate of the cross section for spontaneous and induced positron emission during the formation of a supercritical atom in a heavy-ion collision. Energy and width of the electron levels are taken from an analytical WKB formula.
