摘要：

Deep inelastic neutron scattering measurements on normal liquid He4 at 4.25 K have been carried out at 11 densities between 0.125 (saturated vapor pressure) and 0.200 g/cm3, at a momentum transfer of 23 A-1. A sum of two Gaussians is required to characterize the scattering at all densities, even when the broadening due to instrumental resolution and corrections to the impulse approximation are included. The kinetic energy varies from 15.5 K at 0.125 g/cm3 to 32.7 K at 0.200 g/cm3. © 1990 The American Physical Society.
