DEEP INELASTIC SCATTERING FROM QUANTUM FLUIDS

A simple and general argument is given for the deep inelastic behavior of the dynamic structure function of quan-tum fluids at zero temperature. The resulting high-energy tail is shown to give a reasonable fit to existing neutron data for liquid 4He. Inelastic neutron scattering [e.g. 1] from quantum mentary excitations are not important, the back-fluids at low energy transfers has been used extensive- ground of S(k, w), which arises from real multiexcita-ly as a direct measure of the elementary (density) ex- tions, is given by scatteringfunction citations characteristic of the quantum fluid. At higher energy transfer, more complicated features associated X(k, w) = ~ii~I(4)
