Deep inelastic neutron scattering measurements on normal liquid /sup 4/He at 4.25 K have been carried out at eleven densities between 0.125 (saturated vapor pressure) and 0.200 gm/cm/sup 3/, at a momentum transfer of 23 /angstrom//sup /minus/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 gm/cm/sup 3/ to 3.27 K at 0.200 gm/cm/sup 3/. 24 refs., 9 figs., 2 tabs.
