Theoretical and experimental determination of K- and L-shell x-ray relaxation parameters in Ni

摘要

Fluorescence yields (FY) for the NiK and L shells were determined by a theoretical and an experimental group within the framework of the International Initiative on X-ray Fundamental Parameters (FPs) collaboration. Coster- Kronig (CK) parameters were alsomeasured for the L shell of Ni. Theoretical calculations of the same parameters were performed using the Dirac-Fock method, including relativistic andQEDcorrections.The experimental values for the FY and CK were determined at the PTB laboratory in the synchrotron radiation facility BESSY II, Berlin, Germany, and are compared to the corresponding calculated values.
