Energies, fine structure, hyperfine structure and Auger widths of the core-excited states for the Li isoelectronic sequence

Abstract

The relativistic energies, fine structures, hyperfine structures, Auger rates and widths of the core-excited states for the Li isoelectronic sequence (Z = 10–20) are studied using the saddle-point variational method and the saddle-point complex-rotation method. The oscillator strengths, radiative rates, wavelengths and lifetimes are also reported. Properties such as fine-structure splitting, radiative and Auger rate regularly change along the Li isoelectronic sequence are discussed. The results are compared with other theoretical and experimental data in the literature.
