Stopping power in dense, high-temperature plasmas

Within the framework of density-response formalism and starting from the effective potential which simulates quantum effects of diffraction and symmetry, an expression for the longitudinal dielectric function of semiclassical two-component plasmas is proposed. On the basis of that dielectric function, the stopping power in dense, high-temperature plasmas is calculated. It is found that quantum effects lead to energy loss enhancement when the velocity of an injected particle is small enough. An analytical expression for the stopping power in electron plasmas is obtained in the case of large particle velocity.
