Negative-continuum dielectronic recombination for heavy ions

Abstract

The process of recombination of an electron with a bare heavy nucleus via the creation of a free-positron--bound-electron pair is considered. This process is denoted as ``negative-continuum dielectronic recombination'' because it results in the capture of an incident electron into a bound state accompanied by a transition of a negative-continuum electron into a bound state. The calculations are performed for a wide range of incident electron energies for $Z=82$ and $92.$
