Momentum distribution of liquid 3He: simulation of Deep Inelastic Neutron Scattering experiments with the VESUVIO spectrometer

The recent experimental determination of the 3He single-particle mean kinetic energies in solid hcp, bee 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 3He momentum distributions in pure liquid and in 3He-4He liquid mixtures.
