Electron scattering from Li at 5.4, 10, 20 and 60 eV impact energies

Differential and integral cross sections for elastic scattering and for the excitation of the 2p²P, 3p²P, 4p²P and 3s²S states of lithium have been determined and elastic momentum transfer cross sections have been obtained at 5.4, 10 and 60 eV electron impact energies. The cross sections were normalized to the absolute scale by using the total cross section measurements of Kasdan et al. (1971). The integral elastic scattering cross sections have been compared to calculations utilizing the Glauber and Born approximations and the 2p²P integral cross section results have been compared with optical excitation function measurements and with close-coupling calculations.
