| Abstract: | Energy terms, dipole oscillator strenghts and photoionization cross sections from the ground state are calculated for beryllium-like ions. Autoionizing state transition energies and line widths for the 1P0 resonances in the continuum are also obtained. The configuration interaction method for initial and final states is used, and the atomic orbitals are generated through angular- momentum-dependent, scaled Thomas-Fermi-Dirac potentials. |
