Structure-factor measurements inHe4at saturated vapor pressure for1.38<~T<~4.24K

We present the results of measurements of the liquid structure factor, $S\mathrm{}\left(k\right)\mathrm{}$, for liquid ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ at saturated vapor pressure at seven temperatures between 1.38 and 4.24 K over the momentum-transfer range $k<~5.1$ ${\mathrm{\AA }}^{-1\mathrm{}}$. The results are compared with previous measurements carried out by both x-ray and neutron scattering techniques. Comparison with recent theoretical work emphasizes the importance of higher-order correlations and more realistic potentials in the description of the liquid. Measurements in the vicinity of the $\lambda$ transition document a loss in spatial order as the liquid is cooled through $T_{\lambda }$.
