Popis: | Considering the overlapping among atoms in the molecule and the not full transparency of the molecule by electron, we propose a new formulation of the additivity rule (AR). Here the new AR is employed to calculate the total cross sections (TCS) for electron scattering on hydrocarbon molecules C2H2, C2H4, C2H6 and C3H8 over an incident energy range of 10–2000eV. The results are compared with the experimental data and other available theoretical calculations. This gives good agreement. |
