Electronic excitation of H2 by e+ impact using adiabatic nuclear rotation model.

Abstract

The adiabatic nuclear rotation (ANR) model has been employed to obtain rotational excitation cross sections for electronically elastic and electronic excitation processes in ${\mathit{e}}^{+}$-${\mathrm{H}}_{2}$ scattering. The present results are compared with the more accurate laboratory-frame rotational close-coupling approximation (LFCCA) predictions. The electronically inelastic rotational excitation results using the ANR model differ from the corresponding LFCCA results near the electronic excitation threshold energies. \textcopyright{} 1996 The American Physical Society.
