Within the nuclear-matter approximation, the local-density approximation, and perturbation theory, an approach to constructing a microscopic nucleon-nucleus optical potential at finite nuclear temperatures is developed on the basis of effective density-dependent nucleon-nucleon forces. The real and the imaginary part of the neutron-nucleus optical potential and the mean free paths of neutrons in nuclear matter are calculated at various neutron energies and various nuclear temperatures. The effect of the inclusion of the rearrangement potential on the quantities under consideration is studied, and its importance is demonstrated.
