Abstract

Energy-analysed photoelectrons have been measured in coincidence with product ions from photoionisation of carbonyl sulphide at 21.21 and 40.8 eV photon energy. Yields of the different products and kinetic energy release distributions in fragment ion formation are reported. Results on the states below 20 eV agree with previous work, but our interpretation differs; new data are presented on inner valence states. In dissociation from states in the band at 23 eV there is forward/backward asymmetry in fragment ion direction relative to the electrons, indicating a fast dissociation and possibly identifying the band as a 7σ satellite.
