摘要：

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