Electron scattering by triatomics: and OCS at intermediate energies

Differential, integrated elastic and momentum transfer cross sections have been calculated for the scattering of electrons by and OCS molecules in the energy range 100 - 1000 eV and total cross sections over a wide incident energy range 100 - 4000 eV. A relatively simple approach, namely the independent atom model (IAM) with partial waves has been employed. In the present investigation static, polarization, exchange and absorption effects are taken into account. The present results agree fairly well with the experimental data and other theoretical calculations wherever available.
