Abstract
The bound-free photodetachment cross section of H- is calculated in the length formulation. The bound-state and free-state wavefunctions are calculated to high accuracy using a close-coupling pseudostate expansion with the addition of Hylleraas-type correlation terms. At lower energies the results agree with those of Stewart (1978), to better than 1%, while at ejected electron energies just below the n=2 excitation threshold the results are within 1% of those of Broad and Reinhardt (1976). The shape resonance just above the n=2 excitation threshold is studied, and the partial photodetachment cross sections are compared with those of Hyman, Jacobs and Burke (1972).Keywords
