Abstract

A modified experimental apparatus with improved angular resolution and stability has been used to measure the total electron scattering cross sections for SF₆ and SF₅CF₃ in the energy range of 100-5000 eV. A detailed analysis of the experimental error sources is provided. The experimental results are compared with integral elastic and inelastic cross sections calculated using the independent atom model approximation and a modified single-center additivity rule for electron energies ranging from 1 to 10,000 eV. The accuracy of these approximations method is discussed through a comparison with the experimental results. Previous cross-sectional data for SF₆ are compared with the present theoretical and experimental results. For SF₅CF₃, we present the first electron scattering cross-sectional data for the 100-10,000 eV energy range, as well as the first empirical determination of the molecular polarizability.
