Synopsis Oscillator strengths and integral cross sections (ICSs) of HCl are of great importance for the understanding of many different aspects of atmospheric physics. Based on the generalized oscillator strengths (GOSs) of the valence-shell excitations of HCl measured by the high-energy electron scattering, the optical oscillator strengths (OOSs) have been obtained by extrapolating the GOSs to the limit of the squared momentum transfer K 2 → 0. Furthermore, the ICSs of the valence-shell excitations from the threshold to 5000 eV have been obtained systematically with the aid of the BE-scaling method.
