Calculation of the differential photoionization cross-section of PH3 Original Research Article

Cross-sections, photoelectron angular distribution parameters and branching ratios for the ionization of the outer-valence 5a1, 2e and inner-valence 4a1 shells of phosphine have been calculated up to a photon energy of 90 eV. Ab-initio calculations have been performed, by the K-matrix technique and projection on basis sets of L2 functions, in the random phase approximation for the three coupled ionization channels. The theoretical results, compared with the available experimental data and with recent semi-empirical calculations, show a quantitative agreement with the experiment.
