It is proposed that bound states of ultracold heteronuclear alkali dimer
molecules derived from Feshbach resonances can be efficiently converted into
true ground state ultracold molecules (X v = 0, J =
0) by a stimulated Raman process via b
mixed levels. This is illustrated and discussed for five of the ten
polar heteronuclear alkali dimers: LiNa, NaK, NaRb, RbCs, and especially
KRb.
