Quantum effects on electron-proton bremsstrahlung spectrum in a two-component plasma

Abstract

The electron-proton low energy bremsstrahlung process is investigated in a two-component plasma. The corrected Kelbg potential taking into account the quantum effects is applied to describe the electron-proton interaction potential in a two-component plasma. The straight-line trajectory method is applied to the motion of the projectile electron in order to investigate the variation of the bremsstrahlung cross-section as a function of the scaled impact parameter, thermal de Broglie wavelength, projectile energy, and photon energy. The results show that the quantum-mechanical e ects decrease the bremsstrahlung cross-sections when the de Broglie wavelength is greater than the Bohr radius (a0). It is also found that the quantum e ects are important only for the region of impact parameters b <3a0.
