We present a simple model of ultracold cesium dimer formation in which the photoassociation into rovibrational levels of the double-minimum Cs{sub 2} 3 {sup 1}{sigma}{sub u}{sup +} state above its internal barrier enables spontaneous or stimulated emission into the lowest rovibrational levels of the Cs{sub 2} 1(X) {sup 1}{sigma}{sub g}{sup +} ground electronic state. The transition dipole moment should be sufficiently large for observation of such spectral transitions. The use of the Cs{sub 2} 3 {sup 1}{sigma}{sub u}{sup +} double-minimum potential could be extended to molecular Bose-Einstein condensates in which an optical trap can be employed for trapping of both atomic and molecular species.
