Photoassociation spectroscopy of ultracold Cs below the 6P{sub 3/2} limit
- Department of Physics, University of Connecticut, Storrs, Connecticut 06269 (United States)
High precision photoassociation spectroscopy is performed in ultracold cesium gas, with detunings as large as 51 cm-1 below the Cs(6S{sub 1/2})+Cs(6P{sub 3/2}) asymptote. Trap-loss fluorescence detection is used for detecting the photoassociation to excited state ultracold molecules. Long vibrational progressions are assigned to electronic states of 0{sub g}{sup -}, 0{sub u}{sup +}, and 1{sub g} symmetry. The spectral data are fitted to a LeRoy-Bernstein equation, in order to obtain the effective coefficients of the leading long-range interaction term (C{sub 3}/R{sup 3}) and the relative vibrational quantum numbers measured down from dissociation. Additionally we present evidence for perturbations between the 0{sub g}{sup -} state and the dark 2{sub u} state.
