Dielectronic processes producing radiative stabilization in 150 keV Ne 10+ + He collisions

Abstract

Different contributions to radiative stabilization in the collision 150 keV Ne 10+ + He are discussed. Stabilization is shown to represent 30% of the total double capture. The main contribution (0.51) to stabilization follows from the population of near-equivalent electron configurations 3 l n l ′ ( n = 4, 5) and 4 l n l ′. Further stabilization is due to the decay of configurations 3 l n l ′ of nonequivalent electrons which are populated by means of dielectronic processes during the collision (0.26). The contributions due to configuration interaction in the postcollisional and asymptotic regions are relatively small.
