Abstract
A two-potential localised exchange (TPLE) approach is used to study the role of spin dependence in the inelastic scattering of electrons by lithium atoms at intermediate energies. Results are presented for the spin-resolved orientation parameters (L⊥S,L⊥T, andL⊥) in the polarized-electron impact resonant (2s–2p) excitation of polarized-lithium atom. Results are also obtained for the depolarization (P′e/Pe) in the polarized-electron impact resonant (2s–2p) and nonresonant (2s–3p) transition in unpolarized lithium atom. Further in the case when the fine structure splitting of the target is resolved, we also investigate the left-right scattering asymmetrySA(1/2) for the polarized-electron superelastically scattered from unpolarized 2p1/2 and 3p1/2 states.
