Microscopic structure of liquid hydrogen: a neutron diffraction   experiment
  We have measured the center-of-mass structure factor S(k) of liquid para-hydrogen by neutron diffraction, using the D4C diffractometer at the Institute Laue Langevin, Grenoble, France. The present determination is at variance with previous results obtained from inelastic neutron scattering data, but agrees with path integral Monte Carlo simulations.
