  • 2017 Chinese Physical Society and IOP Publishing Ltd. The self-consistent Hartree-Fock equation for the He atom is solved using the pseudospectral method. The Feshbachtype autoionization resonance parameters for doubly excited 2s2, 3s2, and 4s2 1S states of He have been determined by adding a complex absorbing potential to the Hamiltonian. The Riss-Meyer iterative and Pade extrapolation methods are applied to obtain reliable values for the autoionization resonance parameters, which are compared to previous results in the literature.
