Low energy electron scattering by polar molecules H2S, NH3 and C2H6.

Jayantilal G.Raiyani

In this work we present theoretical study on electron collision with polar molecules in the low energy range, we report, the rotational excitation Differential scattering cross sections (DCS) calculated for electron scattering by polarmoleculesH2S,NH3 andC2H6 in the lowenergy range (5.0-10 eV.).TheBornEikonal Series (BES) approximation method and the hard sphere dipole interaction potential model are used to present electron-molecule interaction. The results obtained are compared with experiment and theoretical data available in the literature.
