Elastic electron scattering by the CF3 radical in the 1–1000 eV energy range

Abstract

Elastic scattering of electrons by a CF3 radical has been studied theoretically in a wide energy range of 1–1000 eV in the framework of an independent-atom model (IAM). The optical potential method is used for calculating the electron scattering amplitudes of the different atoms of the target molecule. The differential and integral cross sections are calculated for equilibrium internuclear distances of the ground state of the CF3 radical in two approaches—IAM and additivity rule (IAM-AR) approximations. The calculated cross sections are compared with the experimental data for e + CF3 and e + CF3H scattering and with other theoretical results. It is justified that the IAM performs slightly better for the differential cross sections, while the simpler IAM-AR approximation describes the integral cross sections better.
