  We model the formation of stable heteronuclear molecules via pulsed Raman
photoassociation of a two-component Bose-Einstein condensate near a strong
Feshbach resonance, for both counterintuitive and intuitive pulse sequencing.
Compared to lasers alone, weak Raman photoassociation is enhanced by as much as
a factor of ten (five) for a counterintuitive (intuitive) pulse sequence,
whereas strong Raman photoassociation is barely enhanced at all--regardless of
pulse sequence. Stronger intra-atom, molecule, or atom-molecule collisions lead
to an expected decrease in conversion efficiency, but stronger ambient
inter-atom collisions lead to an unexpected increase in the efficiency of
stable molecule production. Numerical results agree reasonably with an
analytical approximation.
