Abstract
Radiation from the 2.5 GeV electron synchrotron at the Bonn Physikalisch Institut has been used to measure the spatial distributions of photoelectrons from the molecules N2 and O2. Values of the asymmetry parameter beta of various ionic states have been determined over a photon energy range of 16 to 25 eV using a Seya monochromator to produce plane polarised radiation to a bandwidth of 500 mV. Good agreement with He I and Ne I resonance line measurements by other workers is observed and a comparison with theoretical studies is given. Additional measurements on N2 and C0 which complement the published date of Marr et al. (1979 , 1980) using the Synchrotron Radiation Facility at the Daresbury Laboratory are provided in tabular form.Keywords
