Energies, fine structures, and Auger widths of the high-lying triply excited states of 2S(m) and 2D(m) (m=2—7) for the “hollow atom” lithium

Abstract

The relativistic energies and fine structures of the high-lying triply excited states 2l2l′nl″ 2S(m) and 2D(m) (m=2—7) for the “hollow atom” lithium are studied using the saddle-point variational method and the saddle-point complex-rotation method, including the mass polarization and relativistic corrections. The partial Auger widths and the total widths are also calculated. By the discussion of relativistic effect, we recalibrated the configurations of 2S(7) , 2D(6) and 2D(7).
