Abstract
The absolute photoabsorption cross sections (sigma(t)) and photoioniza tion quantum yields (eta) of alkanes (C2H6 and C3H8) have been measure d in the 50-120 nm region using synchrotron radiation as a light sourc e and an ionization chamber combined with metallic thin film windows. We have evaluated the absolute photoionization cross sections (sigma(i )) and the total cross sections for non-ionizing processes, i.e., the neutral-dissociation cross sections (sigma(d)) following superexcitati on. Several superexcited states have been revealed in these spectra.
