摘要：

The complex Kohn method is used to calculate elastic electron-Li2 scattering cross sections. The effect of including target correlation and polarization is systematically investigated. Various levels of ab initio treatment of the target ground and excited states are shown to have a major influence on the resulting scattering cross section for energies below 1 eV. Comparisions are made with previous calculations and experiment.
