摘要/Abstract

摘要： 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
