Roberts, J. L. and Burke, J. P. and Claussen, N. R. and Cornish, S. L. and Donley, E. A. and Wieman, C. E. (2001) 'Improved characterization of elastic scattering near a Feshbach resonance in 85Rb.', Physical review A., 64 . 024702.
We report extensions and corrections to the measurement of the Feshbach resonance in 85Rb cold atom collisions reported earlier [J. L. Roberts et al., Phys. Rev. Lett. 81, 5109 (1998)]. In addition to a better determination of the position of the resonance peak [154.9(4) G] and its width [11.0(4) G], improvements in our techniques now allow the measurement of the absolute size of the elastic-scattering rate. This provides a measure of the s-wave scattering length as a function of magnetic field near the Feshbach resonance and constrains the Rb-Rb interaction potential.
