Abstract

We have measured the pressure dependence of the supersolid fraction by a torsional oscillator technique. Superflow is found from 25.6bar up to 136.9bar. The supersolid fraction in the low temperature limit increases from 0.6% at 25.6bar near the melting boundary up to a maximum of 1.5% near 55bar before showing a monotonic decrease with pressure extrapolating to zero near 170bar.
