Collective excitation spectra in systems of interacting particles and energy losses in the excitation (within Bose statistics) of collective oscillations during the passage of particles through substances are discussed. Kinetic equations for the distribution quantum function, the collective oscillation spectra in self-consistent field approximation, the influence of particle correlation on collective oscillation and excitation spectra, and the phenomenological theory of degenerate electron Fermi liquid are analyzed. Energy losses related to the excitation of collective oscillations in the medium and the non-linear effects in charged particle passage through plasma are also considered 109 references. (R.V.J.)
