Electron-impact excitation of molecular nitrogen. II. Vibrationally resolved excitation of the C (3)Pi(u)(v(')) state

Vibrationally resolved differential cross sections (DCSs) for electron impact from the X (1)Sigma(+)(g)(v(')=0) ground-state level in N-2 are presented for excitation of the C (3)Pi(u)(v(')) state, where v(')=0, 1, 2, 3, and 4. DCSs for the full C (3)Pi(u)(v(')) state, where v(')=0-4, are also presented. The vibrationally resolved DCSs were obtained from energy-loss spectra in the region of 10.75 to 12.75 eV measured at incident energies of 13, 15, 17.5, 20, 25, 30, 50, and 100 eV and for scattering angles ranging from 5 degrees to 130 degrees. Relative excitation probabilities for the vibrational levels of the C (3)Pi(u) state are shown to demonstrate non-Franck-Condon behavior for excitation energies less than approximately 50 eV. These results are compared with existing measurements.
