DIFFERENTIAL CROSS-SECTIONS FOR ELECTRON-IMPACT EXCITATION OF THE C3-PI-U, E3-SIGMA-G-SIGMA-G+ STATES OF N2( AND A''1)

Differential cross sections for electron impact excitation of the opti cally forbidden C 3PI(u), E 3SIGMA(g)+ and a'' 1SIGMA(g)+ states of N2 have been measured at incident energies of 17.5 and 20 eV and over th e angular range 10 to 100-degrees. Cross sections for vibrational and electronic transitions have been obtained. Integral electronic cross s ections for the C 3PI(u) and E 3SIGMA(g)+ states have also been determ ined. The present results are compared with previous experimental and theoretical studies.
