摘要：
The total cross sections of chlorofluoromethane molecules were measured in the 75-4000-eV range. A comparison is given with existing experimental and theoretical data. The present data and previous measurements in the 15-50-eV range were fitted with a Born-like formula. This simple fit allows the cross sections to be reproduced within experimental errors. Phenomenological double Yukawa scattering potentials can be derived from the formula. A short discussion for the total-cross-section partitioning is given for CF4, CF2Cl2, and CCl4.
