Calculation of the differential photoionization cross-section of PH3

Cross-sections, photoelectron angular distribution parameters and branching ratios for the ionization of the outer-valence 5a(1), 2e and inner-valence 4a(1) 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 L-2 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. (C) 1999 Elsevier Science B.V.
