additivity rule

A semi-empirical additivity rule is presented. Total cross sections ( TCSs) for electron scattering from C_3H_6 isomers: propene ( C_3H_6) and cyclopropane ( c-C_3H_6) have been calculated in 10~ 300eV employing the semi-empirical additivity rule.

我们提出了一个可加性规则的半经验公式，并且运用该公式对10~300eV时C3H6同分异构体电子散射总截面进行了计算。
