Spectrum of elementary excitations of liquid potassium

From the experimental data on liquid potassium inelastic neutron scattering in the temperrature range of (340-550) K the frequency spectrum of atomic vibrations was derived. Using frequency spectrum a number of other microscopic dynamic characterstics such as velocity autocorrelations, atom mean square displacement, atom vibrations mean square amplitude, interatomic potential force constant, mean square force acting on liquid potassium atom in the force neighbours were obtained. 27 refs., 10 figs
