| Popis: | A deep-inelastic (Compton) neutron scattering experiment on ${\mathrm{H}}_{2}\mathrm{O}\ensuremath{-}{\mathrm{D}}_{2}\mathrm{O}$ mixtures at $T\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}293\mathrm{K}$ has been carried out. Well-resolved H and D neutron recoil peaks in the time-of-flight spectra permit the direct determination of the ratio $Q\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}{\ensuremath{\sigma}}_{\mathrm{H}}/{\ensuremath{\sigma}}_{\mathrm{D}}$ of the H and D total cross sections. In contrast to every conventional expectation, $Q$ has been observed to vary strongly with the H-D composition. This striking effect provides, for the first time, direct evidence for short-lived entanglement of adjacent protons (deuterons) in condensed matter at room temperature. |
