Spin asymmetry, alignment, and coherence in electron-lithium resonant excitation

A two-potential localized exchange approach is used to study the coherence and alignment in electron-lithium resonant (2s-2p) excitation processes at intermediate electron energies of 10, 15, and 20 eV. Furthermore, the total and differential spin asymmetry in the resonant scattering of spin-polarized electrons with spin-polarized lithium atoms is also investigated.
