We study the behavior of a hysteretic current-biased Josephson junction in the vicinity of its return to the zero-voltage states, with primary though not exclusive emphasis on the limit of weak damping (..beta../sub J/<<1), and under the assumption that the zero-point and thermal energies are both small compared to I/sub c/phi/sub 0/ so that fluctuation effects are important only very close to the return point. We consider in detail the resistively shunted junction (RSJ) and quasiparticle-tunneling models, and also make predictions for more general models. Denoting the value of imposed current I at which return to the zero-voltage state would take place in the absence of fluctuations by I/sub r/, we study in particular (a) the dc current-voltage characteristic in the running state for I-I/sub r/<
