摘要: The nonresonant cross-section, Fano-shape parameter and coefficient have been calculated for the photoionization of helium heliumlike under threshold residual ions. Dipole matrix elements which correspond to transitions from state continuum 1sp () were determined by choosing, ground state, six-parameter Hylleraas wave function including electron correlation effects a completely screened Coulomb continuum. Energies widths in diagonalization method. results are compared with available obtained other theoretical approaches.
