Efficient formation of strongly bound ultracold cesium molecules by photoassociation with tunneling

Abstract
We calculate the rates of formation and detection of ultracold Cs2 molecules obtained from the photoassociation of ultracold atoms through the double-well 0g- (6S1/2 + 6P3/2) state. We concentrate on two features previously observed experimentally and attributed to tunneling between the two wells [Vatasescu et al 2000 Phys. Rev. A 61 044701]. We show that the molecules obtained are in strongly bound levels (v''=5,6) of the metastable a3Sigmau+ (6S1/2 + 6S1/2) ground electronic state.
