Abstract

Absolute differential cross sections for elastic electron scattering and vibrational, v = 0 → 1, excitation in nitrogen have been measured in the scattering angle range from 10° to 180° and at incident electron energies between 5 eV and 20 eV. The magnetic angle-changing technique has been applied to access the range of scattering angles between 90° and 180°. Integral and momentum cross sections have also been derived by integration of the measured differential cross sections. A comparison with recent theoretical calculations of elastic and vibrational cross sections is presented.
