Angularly and rotationally resolved measurements of photoelectron angular distributions for the X2Ãg+ (v+=0;N+ =0) ground state of para-H2+ are presented, over the photon energy range, 15.47¡V15.75 eV. This range includes most of the autoionising resonances that decay primarily into the ground vibrational ionic state. The measurements were performed using synchrotron radiation, a high-resolution hemispherical analyser and a magnetic angle changer. The value of the asymmetry parameter in this energy interval is close to 2, but sharp variations are observed at particular photon energies.

Abstract
Angularly and rotationally resolved measurements of photoelectron angular distributions for the X2Ãg+ (v+=0;N+ =0) ground state of para-H2+ are presented, over the photon energy range, 15.47¡V15.75 eV. This range includes most of the autoionising resonances that decay primarily into the ground vibrational ionic state. The measurements were performed using synchrotron radiation, a high-resolution hemispherical analyser and a magnetic angle changer. The value of the asymmetry parameter in this energy interval is close to 2, but sharp variations are observed at particular photon energies.File in questo prodotto:
