Abstract

We report measurements of differential cross sections for elastic electron scattering from CF₃. These experiments were performed at nine incident electron energies in the range 7-50 eV and over a scattered electron angular range of 20°-135°. Where possible, results from the present measurements are compared with those from earlier R-matrix and Schwinger multichannel computations, as well as those from an extended independent atom model approach that were calculated as a part of the present study. Agreement with theory is generally good at energies above 20 eV, but for 20 eV and below the magnitude of the measured differential cross sections are significantly larger than those predicted by all the theories.
