Energies, fine structures and transition wavelengths of the core-excited states in Be+ ions

摘要

The fine structures of doubly excited resonances of lithium-like beryllium are calculated using the saddle-point and saddle-point complex-rotation methods. A restricted variational method is used to obtain a more accu- rate value for the nonrelativistic energy. Relativistic and mass polarization corrections to the resonance energy are include- ed. Transition wavelengths are also calculated and compared with other theories and experimental results.
