Since freezing is suppressed in small pores such as those of Vycor, superfluidity occurs at substantially higher pressures than in bulk 4He. Ultrasonic measurements show that the amount of superfluid in the pores does not decrease until freezing begins at a pressure of about 36 bar. At slightly high
After the temperature value of the 3He melting pressure minimum of 315.1 mK has been confirmed by other authors, now the pressure values of the other fixed points of the melting curve are determined. To avoid the limitations due to the uncertainty of the absolut pressure scale it is more precise to
