Modified versions of the dynamic effective interaction potentials for the charged particles in dense semiclassical plasma are presented. These models consider dynamic screening, quantum mechanical effect of diffraction and particle velocity distribution function with non-Maxwellian suprathermal tail. Such distributions are well described by the so-called kappa-distribution and can be used in different space plasma and in some plasma installations where the suprathermal particles take place. Based on this modified dynamic interaction potentials the differential scattering cross sections of the electron-electron and electron-ion collisions were investigated. The obtained results for different values of the density parameter, coupling parameter and spectral index κ are presented.
