Abstract : This work focused primarily on formation of ultracold 87RbCs molecules in their rovibrational ground state by magneto association followed by STIRAP, resulting in 14 papers acknowledging EOARD/AFOSR support (4 in PRL). RbCs was only the second ultracold polar molecule to be produced worldwide. Production of 87RbCs is difficult because large positive scattering lengths make clouds difficult to overlap (but 85RbCs looked promising), but 85RbCs is difficult because 85Rb is hard to produce at high densities. We revealed broad Feshbach resonances that we hope will allow production of higher-density 85Rb clouds. We are now attempting to achieve the next step, formation of 85RbCs molecules.
