The resonance energies and widths of the Be 2pns and 2pnd (1P(superscript o) and 3P(superscript o)) doubly excited states are determined. The densities of the resonance states are calculated by using the stabilization method along with the B-spline-based configuration interaction (BSCI) approach. The results obtained from the stabilization method are in good agreement with those obtained from the B-spline-based complex rotation (BSCR) calculation and other theoretical and experimental results.
