Properties of the Kalpha and Kbeta x-ray transitions in CuXX through CuXXVIII

Transition properties of the Kalpha and Kbeta x-ray from CuXX through CuXXVIII have been calculated by using relativistic configuration interaction (RCI) and multi-configuration Dirac-Fock (MCDF) method in the active interaction approach. The contributions from Breit interaction, quantum electrodynamics (QED) corrections and nuclear mass corrections to the initial and final levels have been taken into account. Through the use of the active space method, the calculated values are compared with the other available data on He-like and Be-like copper and are found to be in very good agreement with them. In this paper, we give accurate transition properties from CuXX through CuXXVIII. These data provide reference value for level lifetime, charge state distribution and average charge of copper plasma.
