摘要
Differential cross sections for the elastic scattering of electrons by H2 at 100 eV and 150 eV have been calculated and compared with experiments.We use the momentum space method in which the electron-molecule system has a single centre and the interaction of electron-nuclei is expanded by a multipole expansion.The static exchange calculation is supplemented by a phenomenological polarization potential.Electron-molecule scattering is reduced to an electronic problem by the Born--Oppenheimer approximation,using closure over the vibrational and rotational states.
