|Title:||Vibronic Excitation Cross-sections For The Χ1Σ+ G(ν = 0) → C1Πu(ν′ = 0,1,2,3) Transitions In H2 By Electron Impact|
|Abstract:||In this work the distorted-wave approximation is applied for a systematic study of the Χ1Σ+ g → C1Πu transition in H2 by electron impact in the 15-60 eV energy range. Adiabatic-nuclei differential and integral cross-sections and branching ratios for the vibronic transitions ν = 0 → ν′ = 0,1,2,3, as well as fixed-nuclei differential and integral cross-sections, are reported. The comparison of our fixed-nuclei results with the available experimental data is encouraging. On the other hand, some deviations from the Franck-Condon approximation are seen, particularly for energies lower than 30 eV. © 1997 Elsevier Science B.V.|
