Abstract:
A magnetic field-dependent Feshbach resonance has been observed in the elastic scattering collision rate between atom in the F = 2, M = −2 state of 85Rb. Changing the magnetic field by several Gauss caused the collision rate to vary by a Factor of 104, and the sign of the scattering length could be reversed. The resonance peak is at 155.2(4) G and its width is 11.6(5) G. From these results we extract much improved values for the three quantities that characterize the interaction potential: The van der Waals coefficient C6, the singlet scattering length aS, and the triplet scattering length aT.
