Abstract

The momentum distribution function, $n(\stackrel{\ensuremath{\rightarrow}}{\mathrm{p}})$, is determined for liquid $^{4}\mathrm{He}$ at 1.00, 2.12, 2.27, and 4.27 K from new neutron inelastic-scattering measurements at large momentum transfers. An improved method for extracting the condensate fraction, ${n}_{0}$, from $n(\stackrel{\ensuremath{\rightarrow}}{\mathrm{p}})$ is presented and used to obtain new values for ${n}_{0}$ at 1.00 and 2.12 K and a revised value at 1.1 K.
