dc.description.abstract | We investigate the electron?ion bremsstrahlung process in astrophysical thermal turbulent plasmas including the influence of the dynamic plasma shielding. The effective interaction potential taking into account the dynamic shielding length and the influence of the plasma turbulence through the diffusion effect with the impact parameter analysis is employed in order to obtain the bremsstrahlung radiation cross-section in turbulent plasmas as a function of the Debye length, diffusion coefficient, impact parameter, projectile energy, photon energy and thermal energy. The results show that the bremsstrahlung radiation cross-section decreases with an increase of the thermal energy for small impact parameters and, however, increases with increasing diffusion coefficient. In addition, the dynamic shielding effect enhances the bremsstrahlung radiation cross-section for small thermal energies. It is also found that the dynamic shielding effect on the bremsstrahlung radiation cross-section increases with an increase of the diffusion coefficient and, however, decreases with increasing thermal energy in astrophysical turbulent plasmas. | en_US |
