J/ApJ/667/1119    Photoionization of H in strong magnetic fields  (Zhao+, 2007)

Hydrogen photoionization cross sections for strong-field magnetic white dwarfs. Zhao L.B., Stancil P.C. <Astrophys. J., 667, 1119-1125 (2007)> =2007ApJ...667.1119Z
ADC_Keywords: Atomic physics ; Stars, white dwarf ; Magnetic fields Keywords: atomic processes - stars: magnetic fields - white dwarfs 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.
