Total cross sections for electron scattering at 10－5000eV by polyatomic molecules CF₄, CF₃H, C₂F₄, C₂F₆, and C₂H₃F₃

The additivity rule and complex optical potential approach have been employed to obtain the total (elastic and absorption) cross sections for electron scattering by molecules (CF₄, CF₃H, C₂F₄, C₂F₆, and C₂H₃F₃) over an incident energy range from 10 to 5000eV. Compared with other calculations and experimental data wherever available, excellent agreement has been obtained. Above 1000eV, there are no experimental dates for CF₃H, C₂F₄, C₂F₆ and C₂H₃F₃, so the present results can provide comparison and foretell for experimental research
