title: Collective dynamics in liquid lead. II. Mode contributions to time correlation functions.
abstract: Mode contributions of different collective excitations to the density-density time correlation function in liquid lead are studied within the nine-variable approach of generalized collective modes. It is shown, that a kinetic relaxing mode, caused by slow density fluctuations, defines almost completely the shape of density-density time correlation function for wave numbers close to the main peak position of the static structure factor. The physical meaning of this mode is discussed.
