We calculate the decay rate ratios for OZI allowed decays of Y(5S) to two B mesons by using the decay amplitudes which incorporate the wave function of the Y(5S) state. We obtain the result that the branching ratio of the Y(5S) decay to [B.sup.*.sub.s][[bar.B].sup.*.sub.s] is much larger than the br...
