The role of internal excitation in affecting electron-molecule cross sections is analyzed fo H2, N2 and O2 systems. Particular emphasisi is given to the role of vibrational energy in affecting both the resonant and non-resonant electron molecule cross sections. In general for resonant transitions the cross sections dramatically depend on the nitial vibrational quantum number of the target, while a minor effect is found for direct (non-resonant) transtions. Cross sections in this last case reflect the form of Franck-Condon factors and Franck-Condon densities linking the relevant bound-bound or bound-continuum transitions. A similar behaviour is presented when the target is electronically excited. In this case, however, the enhancement of cross section is much higher.

Abstract

The role of internal excitation in affecting electron-molecule cross sections is analyzed fo H2, N2 and O2 systems. Particular emphasisi is given to the role of vibrational energy in affecting both the resonant and non-resonant electron molecule cross sections. In general for resonant transitions the cross sections dramatically depend on the nitial vibrational quantum number of the target, while a minor effect is found for direct (non-resonant) transtions. Cross sections in this last case reflect the form of Franck-Condon factors and Franck-Condon densities linking the relevant bound-bound or bound-continuum transitions. A similar behaviour is presented when the target is electronically excited. In this case, however, the enhancement of cross section is much higher.
