Abstract
We present inelastic neutron scattering measurements of liquid He-3-He -4 mixtures at 1.5 K and at He-3 concentrations of 0, 15, 40, 70 and 1 00%. There is little apparent concentration dependence of the He-3 kin etic energy, in disagreement with recent variational calculations for mixtures. The kinetic energy of the He-4 component for the lower conce ntration mixtures is consistent with theoretical predictions.
