Abstract

We report the results of a theoretical study of resonant vibrational-excitation of N2 by low-energy electrons. The vibrational-excitation cross sections were calculated using ab initio fixed-nuclei resonance parameters in the complex-potential or "boomerang" model of Dubé and Herzenberg. The electronic resonance energy and decay width were extracted from several ab initio calculations of the Πg2 shape resonance of N2. The good agreement between the present cross sections and those obtained recently with the R-matrix technique indicates that the assumptions underlying the complex-potential model are valid for the case of N2(Πg2). The present results also show the sensitivity of the computed vibrational-excitation cross sections to the fixed-nuclei resonance parameters employed in the calculations. The differential vibrational-excitation cross sections at 90° and the total integrated cross section which we have obtained agree resonably well with the available experimental data.
