The resonant photoionisation of hydrogen atom in intense magnetic fields

Show affiliations


A complex quasi-energy approach is presented for accurate treatment of photo-ionisation of the H atom in strong magnetic fields. The autoionising resonances near the first two excited Landau thresholds are determined by the complex-coordinate coupled-Landau-channel method. Detailed resonant photoionisation cross sections and asymmetric line shapes are reported for the case of B=4.7*109 G.
