Abstract
In this paper, we calculate the stopping power and temperature relaxation of dense plasmas on the basis of the Coulomb logarithm using the effective potentials. These potentials take into account long‐range multi‐particle screening effects and short‐range quantum mechanical effects in two‐temperature plasmas. Ion energy losses in the plasma for different values of temperature and plasma density are calculated. The obtained results are compared with the theoretical works of other authors and with the results of molecular dynamics simulations.
