Calculations of doubly excited states of beryllium-like ions using the stabilization method

摘要

The resonance energies and widths for doubly excited states of beryllium-like ions are determined by calculating the density of resonance states using the stabilization method. A model potential is used to represent the interaction between the outer electrons and the core electrons. Products of Slater orbitals are used to represent the two-electron wavefunctions. We present results for the two lowest 1s(2)3l3l' D-1(e) doubly excited states for Z = 5-10, and Z = 12. Comparisons are made with other calculations in the literature. [References: 18]
