Photoabsorption and Photoionization of Acetaldehyde in the 10.8-21.4 eV Range.

ABSTRACT: An experimental and theoretical investigation of acetaldehyde's photoabsorption and photoionization in the vacuum-ultraviolet energy range is presented. The absorption cross sections and the ionization efficiency were measured using a double-ion-chamber spectrometer in the 10.8-21.4 eV and 13.5-21.4 eV ranges, respectively. No previous reports of these quantities were found in the literature in this energy range. Photoionization and neutral-decay cross sections were derived from these results. Theoretical calculations were performed using the Padé approximant technique and the single-center partial-wave expansion method, which were applied to solve the Lippmann-Schwinger equation to obtain the asymmetry parameters and the photoionization cross sections for the seven outermost valence orbit
