Theoretical Auger transition energies for atoms and ions through the relativistic and correlated local-density method

Abstract

Theoretical calculations of several Auger, Coster-Kronig, and super-Coster-Kronig transitions of noble gases (such as Ne, Ar, Kr, and Xe) and of transition-metal atoms and their ions are presented using the recently developed relativistic and correlated local-density method [M. Vijayakumar, N. Vaidehi, and M. S. Gopinathan, Phys. Rev. A 40, 6834 (1989)]. The importance of relativistic and correlation effects on these transition energies is discussed. The results are compared with reported experimental results as well as with those obtained by semiempirical and ab initio methods. Predictions are also made of various Auger transition energies for processes like K-LL and L-MM transitions for some ions.
