摘要：

We consider the homogenous nucleation of solid helium from the liquid phase at pressures above the normal freezing pressure. We find that if the liquid-solid surface energy alpha is assumed to be independent of pressure, then at 1 K nucleation should occur at a liquid pressure in the range 60 to 70 bars. Allowance for the variation of a with pressure is found to result in a very large reduction in the nucleation rate.
