Аннотация
The Josephson current (coherent flux of particles and spin) between two reservoirs containing superfluid He3-A is calculated within the framework of the tunnelling Hamiltonian. It is shown that upon rotation of an annular vessel with two orifices a phase increment develops, which is proportional to the angular velocity of the rotation, which velocity periodically modulates the critical liquid flow.
