SPIN-RESOLVED ORIENTATION, DEPOLARIZATION AND LEFT-RIGHT ASYMMETRY INELECTRON-LITHIUM SCATTERING

A two-potential localised exchange (TPLE) approach is used to study th e 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(perpendicular-to)S, L(perpendi cular-to)T, and L(perpendicular-to) in the polarized-electron impact r esonant (2s-2p) excitation of polarized-lithium atom. Results are also obtained for the depolarization (P(e)'/P(e)) in the polarized-electro n impact resonant (2s-2p) and nonresonant (2s-3p) transition in unpola rized lithium atom. Further in the case when the fine structure splitt ing of the target is resolved, we also investigate the left-right scat tering asymmetry S(A)(1/2) for the polarized-electron superelastically scattered from unpolarized 2p1/2 and 3p1/2 states.
