Abstract
Positions and widths of six series of autoionizing states 2pnl of the neutral beryllium atom are calculated (i) by direct solution of 2s-2p close-coupling equations for the system Be+ + e- in the elastic scattering region, and (ii) by solving the same equations above the 2p excitation threshold and using the many-channel quantum defect theory to extrapolate below threshold Results of the two methods are compared. By extrapolation below the 2s threshold, the positions of the bound states of the neutral atom are calculated allowing for configuration mixing.
