Abstract
Landau damping effects on the classical electron–ion Coulomb bremsstrahlung process in dense Maxwellian plasmas are investigated. The electron–ion dynamic interaction potential is obtained by introduction of the longitudinal plasma dielectric function. The classical trajectory method is applied to represent the differential bremsstrahlung radiation cross section as a function of the impact parameter, photon energy, projectile velocity, electron thermal velocity, and Debye length. The Landau damping effect in the soft photon case is found to be more important than that in the hard photon case. It is also found that the Landau damping effect is important when the projectile velocity is equal to the electron thermal velocity (vT/ve=1), for example, the Landau damping effect is about 3.4% for Ep/Ee=0.1.
