摘要/Abstract

摘要： 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 C$_2$H$_2$, C$_2$H$_4$, C$_2$H$_6$, and C$_3$H$_8$ 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.
