Abstract

Based on the differences between superfluid helium and superconductors in the dissipation mechanism of a weakly coupled system, an attempt is made to explain the possibility of observing an ac Josephson effect in superfluid helium with an orifice much larger than the coherence length of the superfluid helium. The temperature criterion for the ac Josephson effect proposed by Biswas is also discussed. The temperature needed for observing an ac Josephson effect in superfluid helium may not have to be much below 1 K.
