Abstract
We present results from two-photon photoassociative spectroscopy of the least-bound vibrational level of the state of the dimer. Measurement of the binding energy allows us to determine the -wave scattering length . For the intermediate state, we use a bound level on the metastable potential, which provides large Franck-Condon transition factors and narrow one-photon photoassociative lines that are advantageous for observing quantum-optical effects such as Autler-Townes resonance splittings.
