Complex Rotated Relativistic Configuration-Interaction Calculations of 1s2l2l ' States in O5+ Ion

Relativistic calculations of the energies and Auger widths of the lowest autoionizing states of lithium-like oxygen are performed. All leading corrections to the energy, including the contribution of electronic correlations, nuclear recoil effect, and quantum electrodynamic (QED) corrections, are in...

More Information
Summary:Relativistic calculations of the energies and Auger widths of the lowest autoionizing states of lithium-like oxygen are performed. All leading corrections to the energy, including the contribution of electronic correlations, nuclear recoil effect, and quantum electrodynamic (QED) corrections, are included. The calculations have been performed using the Dirac–Coulomb–Breit Hamiltonian by the method of configuration interaction with complex rotation. The results obtained have been compared with the known experimental and theoretical values.
