Abstract
We have studied the long term decay of persistent currents in unsaturated 4He superfluid films of thickness 8.1 atomic layers at 1.5 K using pulsed third sound time of flight techniques. The velocity is observed to decay to zero and the functional dependence deviates strongly from the log t behavior observed previously in both film and bulk restricted geometry experiments.
