Cross sections for electron-impact excitation of the electronic states of N2

Creators: Mu-Tao, Lee; McKoy, Vincent

Abstract

Distorted-wave cross sections are presented for the excitations of the w1Δu, W3Δu, A3Σu+, b′1Σu+, and c′1Σu+ states of N2 by low-energy electron impact. The distorted waves are obtained in the static-exchange field of the ground electronic state. Differential and integral cross sections are presented from near threshold up to 60-eV impact. Comparison is made with available experimental data and with other calculations.
