Natural widths, lifetimes, and fluorescence yields for the double K-shell hole states of atoms with 10≤Z≤30

摘要

The natural widths, lifetimes, and fluorescence yields for the double K-shell hole states have been calculated for atoms with 10 ≤ Z ≤ 30. The Grasp2018 package was adopted to carry out a systematic computation of the K~hα_(1,2) and K~hβ_(1,3) radiative transition rates and Fac was used to calculate the KK-KLL, KK-KLM, and KK-KMM non-radiative Auger transition rates. The dependence of the radiative and non-radiative rates on the existence of 3s, 3p, 3d, or 4s spectator holes is studied.
