Quantum screening effects on nonrelativistic electron-ion bremsstrahlung process in two-component plasmas

摘要

Quantum screening effects on the nonrelativistic electron-ion bremsstrahlung process in two-component plasmas are investigated using the corrected Kelbg potential taking into account the classical effect as well as the quantum-mechanical effect. The Born approximation is assumed for the initial and final states of the projectile electron. The results show that the electron-ion bremsstrahlung radiation cross section decreases with increasing the de Broglie wavelength (lambda). The quantum screening effect on the bremsstrahlung cross section increases with increasing the charge (Z) of the target ion. It is also found that the quantum screening effect on the bremsstrahlung cross section increases with increasing the radiation photon energy (epsilon). (C) 2001 American Institute of Physics.
