Influence of oscillatory quantum shielding on scattering-induced spin-asymmetry and spin-channel preference in quantum plasmas

This paper is devoted to the oscillatory screening effect on the electron scattering spin-asymmetry and spin-channel preference in quantum plasmas. It is found that the oscillatory quantum screening effects enhance the spin-singlet electron-scattering channel, but suppress the spin-triplet electron-scattering channel for the forward and backward scattering directions with increasing wave number for small quantum wave numbers. It is also found that the preference of the spin-singlet scattering, including the influence of oscillatory quantum shielding, has been reduced with increasing quantum wave number. The variation of the angular averaged scattering spin-asymmetry phenomenon is also discussed. (paper)
