摘要：

A deep-inelastic (Compton) neutron scattering experiment on H2O-D2O mixtures at T = 293 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 = sigma(H)/sigma(D) of the H and D total cross sections. In contrast to every conventional expectation, Q has been observed to vary strongly with the K-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.
