摘要：

We have investigated the influence of impurities on the possible supersolid transition in He-4 by systematically enriching isotopically pure samples with He-3. The addition of He-3 broadens the onset of nonclassical rotational inertia and shifts it to higher temperature, suggesting that the phenomenon is correlated with the condensation of He-3 atoms onto the dislocation network in solid He-4.
