[en] Results of neutron inelastic scattering studies of liquid ³He at 15 mK have been reported previously. These results are summarized in the present paper which also contains some additional data obtained at smaller wave-vectors. It is shown that for q less than or approximately equal to 1.4 A^-1 the zero-sound mode and the spin-fluctuation spectrum are observed as separate peaks in the scattering function. For q greater than or approximately equal to 2 A^-1 strong evidence is obtained for sharp two-phonon scattering at approximately twice the energy of the flat portion of the zero-sound dispersion curve
