Abstract
For temperatures above the solid ordering temperature TN=0.934 mK, the molar volumes v1 and vs of liquid and solid3He at melting pressure, Pm are determined primarily by the melting pressure and the compressibility. However, in the vicinity of TN and below, vs(T) is influenced greatly by the expansion coefficient, which becomes large and negative. Using existing thermodynamic data, we find that vs(T) has a minimum at TN with a negative slope for T < TN. A constant-volume, all-solid sample starting at T=0 with the pressure just above Pm would begin to melt as TN is approached, becoming all-solid again somewhat above TN.
