    Notes: Abstract Momentum conservation equations for the viscous fermi-liquid are derived from the kinetic Landau Vlasov equation with taking into account the retardation effects in the collision integral. Viscosity coefficients for the longitudinal and transversal zero sound in nuclear matter have been calculated. Results obtained in the semiclassical macroscopic nuclear model are compared with phenomenological values of the viscosity coefficients fitted to experimental data for the mean kinetic energies of fission fragments.

    Notes: Abstract We expand the nonmarkovian collision integral in terms of multipolarities of the distortion of the Fermi surface. It is shown that damping of zero-sound is determined by all multipolarities of the Fermi-surface deformation. For large zero-sound velocity with respect to the Fermi velocity the relaxation time is related to the quadrupole deformation of the Fermi surface. The contributions of collisions to the total widths of the giant multipole resonances are calculated in a semiclassical macroscopic nuclear model.
