Neutron measurements of the single-particle kinetic energies in solid neon

Direct measurements of the mean atomic kinetic energy of solid neon have been made at 16 temperatures in the range 5-22 K and saturated vapor pressure. The measurements were made at high momentum and energy transfers using the technique of neutron Compton scattering. These extensive data have been compared with published calculations, and there is general agreement. The ground-state kinetic energy in condensed neon has been determined to be 41(2) K.
