Abstract

ON March 7, we succeeded in liquefying helium by using an apparatus based on the Simon expansion principle. We obtained with one expansion, starting from a pressure of 80 atm. and a temperature of 14.6° K., a quantity of about 65 c.c. of liquid helium. The maximum capacity of our apparatus is about 120 c.c. It was also possible to lower the temperature to 3.3° K., by reducing the pressure above the helium.
