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
We report new high precision data on the velocity of second sound close to the lambda transition of 4He at the saturated vapor pressure. The second sound wave is detected by a powdered salt pill of copper ammonium bromide in direct contact with the liquid helium. With a thermometer noise of < 10-1Β°K
