Abstract
The influence of plasma turbulence and exchange corrections due to the spin-channel preference on the electro-electron scattering is investigated in turbulent plasmas. The second-order Eikonal analysis and the effective potential including the far-field interaction term caused by the field fluctuation is applied to obtain the total scattering phase shift in turbulent plasmas. The forward and exchange scattering amplitudes for electron-electron scatterings in the spin-triplet and singlet states are obtained by the Glauber-Eikonal method with the impact-parameter analysis. The differential electron-electron scattering cross section for the total spin states of the scattering system is obtained as a function of the Dupree-turbulence coefficient, impact parameter, collision energy, thermal energy, and Debye length in turbulent plasmas. It is found that the turbulent effect enhances the differential scattering cross section, especially, in forward and backward scattering regions. It is also shown that the differential scattering cross section decreases with an increase of the plasma temperature. In addition, it is found that the influence of spin-dependent quantum interference suppresses the scattering cross section due to the fermionic behavior of plasma electrons.
