ATOMIC AND MOLECULAR MOMENTUM DISTRIBUTIONS IN QUANTUM FLUIDS BY NEUTRON COMPTON-SCATTERING

Neutron Compton Scattering (NCS) measurements can provide direct infor mation about mean kinetic energy of molecules in quantum fluids. The p rincipal tool in interpreting NCS experiments is the Impulse Approxima tion (IA). A different approach to the scattering process, which takes into account the exact total energy of the initial state and the aver age potential energy of the final one, is investigated. This approach describes experimental data for a quantum molecular fluid (D-2) more p recisely than IA.
