Abstract:
A recently developed computational scheme, based on the
complex-rotation method combined with a mixed Slater-Landau basis
expansion, has been applied to calculations of photoionization from
atomic hydrogen ground and excited states in a strong magnetic field
typical of magnetic white dwarf stars. Photoionization cross sections
are presented for the twelve states, 1s0, 2s0, 2p0, 2p-1,
3s'0, 3p0, 3p-1, 3d'0, 3d-1, 3d-2, 4f-2, and 4f-3,
with magnetic field strengths from 23.5 to 2350MG.
