Intensive studies of the properties of dense plasma were triggered by the idea of realization of inertial confinement fusion [1-2]. Knowledge about transport and dynamic properties of such dense plasmas is needed to understand experimental results and to design new experiments. In this work, we present the results of calculations of the transport and relaxation properties of dense plasma at ICF parameters. Transport and relaxation properties are studied on the basis of screened electron-ion interaction potentials [3-4]. A pseudopotential approach was used to study the effect of an ionic core on the electron-ion scattering in dense plasmas. Screening of the ion charge is taken into account using the density response function in the long wavelength limit [5-6]. Additionally, the effect of electronic non-ideality is included using the compressibilty sum-rule connecting the local field correction and the exchange correlation part of the electronic free energy density. Using screened pseudopotential, we have computed electron-ion scattering phase shifts, the total elastic scattering cross section, and the transport cross section. It is found that the ionic core leads to the strong decrease of the scattering cross sections, transport, relaxation properties. To show the correctness of the model, its results are compared with the results of MD and QMD simulations [7].
