The mean-field-driven expansion of a BEC was used to measure the scattering length α in 87Rb as a function of the magnetic field in the vicinity of the Feshbach resonance near 1007 G. The position and width of the resonance were extracted from the data. Despite the fact that the resonance is very narrow, the variation of α over a wide range was clearly demonstrated.
