The inelastic scattering of neutrons by liquid ³He at 0.2 K and saturated vapor pressure has been measured for momentum transfers in the range 10 A^-116 A^-1. The observed scattering function is well described, within statistical uncertainties, by a Gaussian centered at the recoil energy. The average kinetic energy per atom, obtained from the width of the scattering function, is 8.1_-1.3+1.7 K.
