Calculation of the differential photoionization cross section of HF Original Research Article

Cross sections, photoelectron angular distribution parameters and branching ratios for the ionization of the valence 1π, 3σ and inner-valence 2σ shells of hydrogen fluoride have been calculated in the Random Phase Approximation (RPA). The computational procedure is based on the K-matrix technique and projection on basis sets of L2 functions to solve the RPA equations for the three coupled ionization channels in a way that recovers the electronic continuum degeneracy.
