Physics of dense semiclassical plasma is one of the fundamental areas of modern physics, in view of the fact that the study of the properties of such plasma is of considerable interest in connection with studies of natural phenomena occurring in astrophysical objects, the creation of scientific foundations for new plasma technologies and the problem of controlled thermonuclear fusion. In this work we study kinetic processes of dense semiclassical plasma on the basis of the effective interaction potential of particles, taking into account the quantum-mechanical effects of diffraction and the screening effect. Kinetic characteristics of dense semiclassical plasma are obtained numerically using the Coulomb logarithm on the basis of effective potential. The dependence of electron distribution function on the velocity and the dependence of the average electron energy on the velocity were obtained in a strong field. It has been determine that the particle distribution function in a strong field increases with decreasing plasma density parameter, which is connected with into accounting quantum mechanical effects and screening effect. It has been shown that if the quantum-mechanical effects of diffraction and screening effects in dense semiclassical plasma are taken into consideration, then the average electron energy in a strong field would have increase with increasing plasma particles velocity and then the electron free length path curve would have minimum.
