Abstract
Neutron inelastic scattering experiments have been performed on liquid3He at saturated vapour pressure and T = 1.4 K covering a wide range of energy and momentum transfers (9 ⩽ Q⩽ 20 A−1). Allowing for the very strong3He neutron absorption, the data is of excellent quality and it has been analysed to extract information on the scattering function widths, peak positions and single particle kinetic energies. It is found that there are no width oscillations with momentum transfer and that the average atomic kinetic energy is approximately 20% lower than theoretical predictions, in agreement with previous neutron scattering results. A new method of analysis aimed at extracting both the atomic momentum distribution and final state effects is also presented and the results discussed in the light of current theory.
