Absolute oscillator strengths for the photoabsorption and partial photoionisation of hydrogen fluoride

The absolute dipole oscillator strengths (cross sections) for the partial and total photoionisation of hydrogen fluoride have been obtained in the 5-60 eV photon energy range by magic-angle dipole (e, 2e) spectroscopy. Total photoabsorption oscillator strengths (cross sections) are determined up to 150 eV. Photoelectron branching ratios for the X 2 Pi , A 2 Sigma + and B 2 Sigma + ionic states of hydrogen fluoride are also reported. Comparison of experimental partial oscillator strengths (cross sections) for the X 2 Pi , A 2 Sigma + and B 2 Sigma + states, respectively, with sophisticated theoretical calculations show generally good agreement over the reported energy range.
