    "abstract": "A magnetic field dependent Feshbach resonance has been observed in the\nelastic scattering collision rate between atoms in the F = 2, M = -2 state of\n85 Rb. Changing the magnetic field by several Gauss caused the collision rate\nto vary by a factor of 10,000, and the sign of the scattering length could be\nreserved. The resonance peak is at 155.2(4) G and its width is 11.6(5) G. From\nthese results we extract much improved values for the three quantities that\ncharacterize the interaction porential: the van der Waals coefficient C6, the\nsinglet scattering length, and the triplet scattering length.",
