Abstract
The low-q part (1 < q/nm(-1) < 5.5) of the structure factor S(q) of Kr has been measured at five densities below 4.3 nm(-3) by means of neutron diffra ction. The three-body interaction contributions to the low-q structure are reliably extracted from the density dependence of the data, leading to the best experimental determination of the Axilrod-Teller forces in a rare-gas fluid.
