Abstract: Quantum effects on the water proton dynamics over the surface of ahydrated protein are measured by means of broadband dielectricspectroscopy and deep inelastic neutron scattering. Dielectricspectroscopy indicates a reduced energy barrier for a hydrogenatedprotein sample compared to a deuterated one, along with a large andtemperature-dependent isotopic ratio, in good agreement withtheoretical studies. Recent deep inelastic neutron scattering data havebeen reanalyzed, and now show that the momentu
