    "abstract": "We report extentions and corrections to the measurement of the Feshbach\nresonance in 85Rb cold atom collisions reported earlier [J. L. Roberts et al.,\nPhys. Rev. Lett. 81, 5109 (1998)]. In addition to a better determination of the\nposition of the resonance peak (154.9(4) gauss) and its width (11.0(4) gauss),\nimprovements in our techniques now allow the measurement of the absolute size\nof the elastic scattering rate. This provides a new measure of the s-wave\nscasttering length as a function of magnetic field near the Feshbach resonance\nand contrains the Rb-Rb interaction potential.",
