Observation of mass transport through solid 4HePhysics Review B
AbstractBy use of an experimental design that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the dc transport of mass through a cell filled with solid 4He in the hcp region of the phase diagram. Flow, which shows characteristics of a superflow, is seen to be independent of the method used to grow the solid but depends on pressure and temperature. The temperature dependence suggests the possibility of hysteresis.
