Differential cross sections for elastic and inelastic scattering of electrons by N2O in the range from 10 to 80 eV

Abstract
Differential electron impact cross sections (DCS) for the elastic scattering and excitation of the 1 Pi and 21 Sigma + states of N2O have been measured using a crossed electron beam-molecular beam scattering technique. These measurements were performed at electron impact energies of 10 and 12 eV for elastic as well as at 15, 20, 30, 50 and 80 eV for elastic and inelastic scattering. DCS were obtained over a wide range of scattering angles, up to 150 degrees . The elastic DCS were put on an absolute scale by normalisation to the total electron scattering cross sections. The inelastic DCS are in relative units except for the case of 80 eV impact energy where it was possible to determine the elastic to inelastic intensity ratio and to obtain absolute DCS values. By extrapolation of DCS to zero and 180 degrees scattering angles, integral and momentum transfer cross sections were obtained.
