Cross sections and asymmetry ({beta}{sub {ital n}{ital l}}) parameters for the photodetachment of 2{ital s} and 2{ital p} electrons from He{sup {minus}}(1{ital s}2{ital s}2{ital p}){sup 4}{ital P0} are calculated using the multiconfiguration Hartree-Fock method which includes the effects of dynamical core polarization and electron correlation. The excellent agreement with limited experimental data suggests its accuracy over the energy range from 0 to 4 eV. The photodetachment cross sections are used to calculate the inverse radiative attachment cross sections.
