TOTAL CROSS SECTIONS FOR THE EXCITATION OF THE TRIPLET STATES IN MOLECULAR NITROGEN
Abstract
A consistent set of total cross sections for electron impact excitation of seven triplet states of molecular nitrogen from the X singlet Sigma(+)(g) state was calculated quantum mechanically for incident electron energies from threshold to 80 eV. The Ochkur-Rudge exchange scattering and Franck-Condon approximations were employed to obtain these cross sections. Minimum and double-minimum basis set LCAO-MO wavefunctions centered on the nuclei were used and the multicenter terms in the scattering amplitude were evaluated using a zeta function expansion. Rotationally averaged cross sections were calculated for excitation from v in. = 0 to individual v ft. - levels of the excited electronic states. The relative magnitudes of these excitation cross sections lead to interesting predictions concerning N2 processes in the upper atmosphere.
