Abstract
Classical electron-ion Coulomb bremsstrahlung process is investigated in classical nonideal plasmas using effective pseudopotential model taking into account the plasma screening and collective effects. The straight-line trajectory method is applied to the motion of the projectile electron in order to visualize the variation of the differential bremsstrahlung radiation cross section (DBRCS) as a function of the scaled impact parameter, nonideal plasma parameter, projectile energy, photon energy, and Debye length. The results show that the DBRCS in ideal plasmas described by the Debye-Huckel potential is always greater than that in nonideal plasmas, i.e., the collective effects reduce the DBRCS for both the soft and hard photon cases. For large impact parameters, the DBRCS for the soft photon case is found to be always greater than that for the hard photon case.
