摘要：

The liquid structure factor of helium-4 has been determined in the momentum-transfer range 0.2 to 0.8 -1. At 0.32 K the structure factor exhibits a gentle but decided change of slope near 0.4 -1 in qualitative agreement with certain theoretical predictions. Below 0.4 -1 the liquid structure factor agrees with that deduced from the Bijl-Feynman dispersion relation. At 4.99 K and 680 mm pressure we have shown that helium gas is distinctly nonideal. © 1969 The American Physical Society.
