Numerical calculations of photoassociation of cold $^{85}$Rb$_{2}$ molecules to the 1_{g}(5P_{1/2})$ State

Data obtained at the University of Connecticut by Jianbing Qi, Dajun Wang, Ye Huang, H. K. Pechkis, E. E. Eyler, P. Gould and W. C. Stwalley in 2003 have been only partially analyzed and assigned. In [1], transitions observed by Qi et al. to the $0_{u}^{+}$ state were presented. Ref. [2] analyzed transitions of $^{87}$Rb$_{2}$ to the ${1_{g}(P_{1/2})$ state, simplified by double spin polarization, observed in the D. Heinzen Laboratory. Transitions to $0_{g}^{-}$ and $1_{g}$ levels without double spin polarization are more problematical. This is a preliminary report, based on data obtained by Qi et al. with a dense array of spectral lines, having certain signal:noise limitations. \\ 1. T. Bergeman {\it et al.}, J. Phys.
