Annotation

Space dispersion of structure relaxation in simple liquids is investigated on the basis of the concept of reduced description. The microscopic formulas are obtained and dispersion curves found for the half-width of the dynamic structure formula. The space dispersion is also obtained for four other relaxation parameters of structure relaxation, viz. the relaxation time tau-s, structure lifetime tau-ls, memory lifetime tau-lm and the parameter epsilon = tau-ls/tau-lm which characterizes the <> or <> of the molecular memory. The dispersion of the set of the five relaxation parameters (tau-s, tau-ls, tau-lm, DELTA-omega-1/2, epsilon) as well as the dispersion of the non-Markovian behavior of the structure relaxation and its transition to the quasi-Markovian regime in a small region of wave vectors near the de Gennes narrowing and maximum of the static structure factor are determined.
