摘要：

Deep inelastic neutron scattering measurements have been carried out to measure the kinetic energy and condensate fraction in liquid He-3-He-4 mixtures. Samples with He-3 concentration on the order of 10% were studied at 1.4 K and 2.3-2.5 K. The condensate fraction was found to be 0.18 +/- 0.03, much larger than theoretical predictions. The measured kinetic energies of the He-3 and He-4 in the mixture remain the same as their values in the pure phase, in disagreement with current theoretical predictions.
