Electron energy distribution in nonideal coulomb systems: theory and results of a numerical experiment

The electron energy distribution function is calculated for the Coulomb model with a plateau under the conditions of significant Coulomb nonideality and compared with the results of numerical simulation. The theory and numerical experiment are found to be in satisfactory agreement. The performed analysis revealed that the density of states in the nonideal Coulomb model with a plateau is a continuous and monotonic function of energy and contains no anomalies. At negative energies, it corresponds to the classical bound states and continuously passes into the density of states of free particles through the region of quasibound states, which was theoretically predicted earlier.
