Superfluid Transition of 4He Films Adsorbed on Porous Vycor Glass
Abstract
The temperature variation of the superfluid density has been measured for 4He films adsorbed on porous Vycor glass. Films with transition temperatures ranging from 0.1 to 1.5 K were studied. Apart from a small rounding on the order of 5×10-3Tc, the superfluid density of these films follows a power law near the transition similar to bulk helium.
