Momentum Distribution of Liquid 3He: Simulation of Deep Inelastic Neutron Scattering Experiments with the VESUVIO Spectrometer

The recent experimental determination of the 3 He single-particle mean kinetic energies in solid hcp, bcc and dense liquid phases has allowed to perform an accurate test of the single-particle dynamical properties derived from the existing theoretical models. A Monte Carlo simulation of a Filter-Difference neutron spectrometer for Deep Inelastic Neutron Scattering with enhanced resolution performance is presented. It aims to study the feasibility of an accurate experimental determination of the 3 He momentum distributions in pure liquid and in 3 He- 4 He liquid mixtures.
