摘要：

We present an experimental and path integral Monte Carlo study of the single-molecule dynamics in fluid parahydrogen. The experiment consists in an inelastic neutron scattering determination of the translational kinetic energy, [E(k)], as a function of temperature at a density close to the triple point. Experimental and simulated values of [E(k)] are found to be in good agreement in the investigated temperature range. Discrepancies are found with a simple harmonic model parametrized by the value of the zero-point kinetic energy.
