Abstract
The effects of relativity on resonance contributions to electron-impac t ionization of Ar15+, Fe23+, Kr33+, and Xe51+ are investigated. The e ffects of relativity are found to increase the resonance strengths by 20% for Fe23+ and by as much as a factor of 3 for Xe51+. The magnetic quadrupole (M2) radiation for the 1s2s2P3/2 J=5/2 metastable state dep ends strongly on the atomic number, varying as Z8. We find that includ ing the M2 emission for the 1s2s2p3/2 J=5/2 state is essential for obt aining reliable cross sections for ions with Z greater-than-or-equal-t o 26.
