Abstract: We report on the observation of time-domain interference with Bose–Einstein condensates, by means of a double separated oscillator technique. We discuss the decay of the Ramsey
oscillations amplitude, that in our system occurs on a time scale of tens of microseconds. To elucidate the origin of this fast decay, we compare the behaviour of a condensate with
that of a thermal cloud.  2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS
