Abstract

Neutron scattering from liquid helium at large energy and momentum transfers was found to be qualitatively consistent with an independent particle model. No evidence for a sharp peak related to the occupation of the zero momentum state was observed but, from the temperature dependence of the width, a value of (17 ± 10)% for the population of this state was deduced. Possible evidence for vortex creation accompanying the scattering process was obtained.
