摘要：

A microscopic theory of Josephson tunneling in weakly interacting BECs is presented. The given theory is essentially the analog within Bogoliubov theory of the standard work by Ambegaokar et al. on the tunneling Hamiltonian description of the Josephson effect between BCS superconductors. It is shown through calculations that the ac Josephson effect might be observable with currently available techniques for 23Na or lighter atoms.
