Abstract

The stopping power of dense nonideal plasmas is calculated in different many-body approximations. The T-matrix approximation of binary collisions is compared with the random phase approximation (RPA) approximation of dielectric fluctuations. It is found that RPA contributions are more important for dense plasmas at low temperatures. Within a microscopic model, the dynamical evolution of the velocity of the projectile is calculated. It reproduces experimental values well for the stopping of fast heavy ions at times after a pinch discharge. Further improvements due to memory effects and relaxation fields are discussed. A renormalization of the effective energy transfer by memory effects is presented.
