Abstract
In this work, studies have been carried out to investigate theoretically the electron (positron)-impact-induced 2s → 2p lithium (Li) transition at 20 and 60 eV using the coupled-channel optical method (CCOM). The inelastic differential cross sections (DCS) together with the reduced Stokes parameters (\(\bar P_1\), \(\bar P_2\), \(\bar P_3\)) and other parameters such as the alignment (γ, \(\bar P_l\)), orientation (L ⊥) and coherence parameters (P +) are reported in the present calculations. Comparison is made with other available theoretical and experimental measurements.
