RESONANCES IN THE ELECTRONIC EXCITATION OF MOLECULAR-HYDROGEN

Ab initio R-matrix scattering calculations are presented for electron-H2 collisions for energies up to 30 eV. Excitation from the ground state, X 1g+, to five accurately represented, low-lying electronic states, b 3u+, a g+, B 1u+, c 3 u, and C1u, is explicitly considered. An attempt is made to rationalize the wealth of experimental ata. Resonance structures similar to those assigned experimentally to the a and c series are found as well as a number of other resonancelike features. © 1990 The American Physical Society.
