Abstract
We have detected a new type of resonance in superfluid He-4. This invo lves the adiabatic motion of the superfluid in and out of a superleak sealed at one end. We detect the resonance by measuring the temperatur e oscillations of the superleak. These measurements yield the superflu id fraction of confined helium. We compare data for a 2113 Angstrom pl anar superleak with earlier results obtained using a torsional oscilla tor technique, and a similar confinement geometry.
