摘要
Ve systematically study the decay properties of the K-shell excited F-like ions with 10≤Z≤36 based on the multiconfiguration Dirac-Fock method.The Breit interaction,the QED corrections and the nuclear finite mass effects are also considered as perturbation.Auger transition rates,radiative,Auger and natural widths,as well as fluorescence and Auger yields for K-shell excited F-like ions are presented.It is shown by means of concrete figures that the decay properties change significantly with the increase of the atomic number Z;the Auger rate is overtaken at Z =30 by the radiative decay rate.Several fitting formulae for the radiative and Auger widths and the fluorescence yields have been evaluated which is expected to be useful in plasma analysis and plasma modeling.
