Title: Stopping power for a charged particle moving through three-dimensional nonideal finite-temperature electron gases

Abstract

We investigate the interaction of a charged particle with nonideal 3D electron gases by using the quantum hydrodynamic (QHD) theory. The stopping power for a nonideal electron gas at a finite-temperature has been theoretically analyzed and numerically calculated. In our calculation, the impact of nonideality and temperature on stopping power is stressed and clearly presented. The QHD dielectric function is obtained and compared to random-phase approximation result. It is shown that the QHD theory can properly describe the stopping power for higher particle velocities greater than the Bohr velocity.
