Possible differences between free and bound protons may be observed in the ratio of polarization-transfer components, P'x/P'z. We report the measurement of P'x/P'z, in the 2\textrmH(e,e′p)n reaction at low and high missing momenta. Observed increasing deviation of P'x/P'z from that of a free proton as a function of the virtuality, similar to that observed in \hefour, indicates that the effect in nuclei is due to the virtuality of the knock-out proton and not due to the average nuclear density. The measured differences from calculations assuming free-proton form factors (∼10%), may indicate in-medium modifications.
