✦ Synopsis

Neutron Compton scattering (NCS) results obtained from liquid hydrogen and hydrogen-deuterium mixtures at 20 K are presented. The measurements have been repeated changing the scattering geometry and employing various experimental setups. The results exhibit the following striking effect. By comparing the recoil-peak intensities for H and D in the mixtures, a strong anomalous shortfall (up to ca. 30%) of the ratio of H and D cross-sections is found, which is rather independent of the scattering angle y: A related (but systematically y-dependent) anomaly is also observed in the ratio of the recoil-peak intensities of H and Al (the latter being due to the sample cell). This effect was previously observed in other materials, too, and it was proposed to be caused by short-lived quantum entanglement involving protons in condensed matter.
