Abstract
The effects of 3-phonon processes on the excitations in liquid at °K are taken into account in a formalism based on the method of correlated wave functions combined with Green's function theory. The connection between the properties studied and experimental data from neutron scattering is discussed. In the high-momentum limit, the equations which describe the excitations are solved and numerical results are presented.
