Differential Cross Sections for Elastic Scattering of Low－Energy Electrons by O2

Differential cross sections for the elastic scattering of electrons by oxygen molecule are calculated for selected impact energies 7eV and 9eV. The results are compared with other theoretical results and experimental data.The present results are obtained by the momentum space optical potential method. This method take the polarization of target states into account, which is very important for the scattering problem, particularly at low energies.
