A pseudopotential model permitting calculation of the characteristics of the microfield of free charges in a nonideal degenerated plasma is proposed and substantiated. The correlation of the positions of the particles, which is governed by the Coulomb interaction of charges, is taken into account exactly, and the quantum effects in the interaction of electrons and ions are taken into account in a pair approximation. The distribution functions of the microfield at positively and negatively charged and neutral points are calculated by the Monte Carlo method. The range of parameters in which the formally calculated number of charges in a Debye sphere varies from 1 to 0.1 is examined. Spatial correlation functions of the microfield are obtained. Corrections due to the difference of pseudopotentials of individual chemical elements at small distances, many-particle quantum effects, and isolation of bound states in the system of electrons and ions are discussed.
