Cross sections for 11-14 eV e-H2 resonant collisions: vibrational excitation (literal)

Abstract

Resonant vibrational excitation ?RVE? cross sections have been calculated for the electron-H2 molecule collisions in the energy range 11-14 eV involving the 2?Sigma_g+ excited electronic state of the molecular hydrogen ion H2-. This state, whose threshold is located around 14 eV, gives rise to the so-called series a of the observed peaks in electron-impact differential cross-section measurements. The calculations have been performed within the local complex potential approximation by using the available theoretical potential energy and width for the 2Sigma?_g+ resonant state. The cross sections for all vi=0->vf=1-14 RVE transitions have been calculated. A satisfactory agreement of calculated cross sections with the available experimental data is obtained. (literal)
