Identification of Ka X-ray Satellite Lines Induced by MeV Heavy-ion Bombardment of Elemental Targets

Abstract

It is shown that multiply ionized atoms with one or two holes in the 2s subshell in addition to holes in the 2p subshell may contribute directly to the observed Krx. satellite and hypersatellite spectra reported for targets bombarded with highly energetic heavy ions. The direct participation of such defect configurations results because the normally rapid Ll -L23M Coster-Kronig transition processes are energetically forbidden for most excited atomic species that are multiply ionized in the L shell. Adiabatic nonrelativistic Hartree-Fock calculations are presented to support this conclusion. A detailed calculation for the Krx. satellite and hypersatellite spectra of the silicon system is given.
