Landau damping effect on elastic collision in uniformly magnetized plasmas

Abstract

The Landau damping effect on electron-ion elastic collision in uniformly magnetized dense plasmas is investigated. The scattetingg phase and cross section for electron-ion elastic collisions in magnetized plasmas are obtained by introduction of the longitudinal plasma dielectric function with the eikonal method. The domains of the velocity, frequency. and impact parameter for the Landau damping effect on the scattering cross section are discussed. It is also found that the Landau damping effect reduces the collision cross section and is more significant when the projectile velocity is greater than the electron thermal velocity.
