(E,2E) MEASUREMENTS FOR VALENCE AND INNER VALENCE ORBITALS OF N2O S. J. Cavanagh and Birgit Lohmann School of Science, Griffith University, Nathan Queensland 4111 AUSTRALIA The (e,2e) technique has been used to investigate the electron impact ionization of nitrous oxide, N2O. The measurements were performed in asymmetric coplanar geometry in order to investigate the ionization dynamics. Results are presented for ionization of the valence 2pi orbital and the inner valence 4sigma orbital.
