Abstract
We analyze the dynamics of a dilute, trapped Bose-condensed atomic gas coup led to a diatomic molecular Bose gas by coherent Raman transitions. This sy stem is shown to result in a new type of "superchemistry," in which giant c ollective oscillations between the atomic and the molecular gas can occur. The phenomenon is caused by stimulated emission of bosonic atoms or molecul es into their condensate phases.
