Z dependence of radiative and Auger transitions rates from doubly excited 3l3l ' states of helium-like ions

摘要

X-ray and Auger transition rates, transition energies, fluorescence yields, and nonradiative branching ratios are calculated for doubly excited 3l3l' configurations of helilum-like chromium and nickel. The calculation has been performed using Hartree-Fock-Slater atomic model. Intermediate coupling and configuration interaction have been taken into account. The energies and widths are found to be strongly affected by configuration interaction. The Z dependence of transition rates are investigated for ions with atomic number Z = 10, 14, 18, 20, 22, 24, 26, and 28 using the present theoretical data and the data from some of our previous calculations.
