Photoelectron angular distributions of the N2O outer valence orbitals in the 19ndash;31 eV photon energy range

摘要

Photoelectron asymmetry parameters, partial cross sections, and branching ratios for theX,A,B, andCstates of N2O+were measured using synchrotron radiation in the photon energy range 19ndash;31 eV. Vibrationally averaged data are reported for all four states, as well as vibrationally resolved data for theAandCstates. The data are compared with a multiple scattering calculation, (e,thinsp;2e) dipole measurements, and similar data on CO2. The N2O and CO2results show remarkable statehyphen;byhyphen;state similarity in their asymmetry parameters.
