Abstract
We have measured the moment of inertia of hcp crystals from 25 mK to 2 K. With a precision of five parts in we find no evidence for a nonclassical rotational inertia. This indicates that if a supersolid exists, it has a of less than 5 × , a transition temperature of less than 25 mK, or a critical velocity of less than 5 μm/sec.
