Neutron inelastic scattering from liquid helium-3

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
