  We consider the dissociation of a molecular Bose-Einstein condensate during a
magnetic-field sweep through a Feshbach resonance that starts on the molecular
side of the resonance and ends on the atomic side. In particular, we determine
the energy distribution of the atoms produced after the sweep. We find that the
shape of the energy distribution strongly depends on the rate of the
magnetic-field sweep, in a manner that is in good agreement with recent
experiments.
