Differential cross sections for elastic electron scattering in xenon in the energy range from 5 eV to 10 eV

摘要

Differential cross sections for elastic electron scattering in xenon have been measured at the energies of 5, 7.9, and 10 eV over the scattering angle range from 30 degrees to 180 degrees. For the measurements in the backward-angle scattering range the magnetic angle-changing technique has been employed. The differential cross sections obtained have been integrated to yield the elastic integral and momentum transfer cross sections. A detailed comparison of the present differential and integral cross sections is made with the existing experimental data and the results of various theoretical calculations. This comparison indicates that the theoretical results achieve a better overall agreement with the experimental cross sections in the backward scattering region than for the case of argon.
