摘要：

A magnetic field-dependent Feshbach resonance has been observed in the elastic scattering collision rate between atoms in the F = 2, M = -2 state of Rb-85. Changing the magnetic field by several Gauss caused the collision rate to vary by a factor of 10(4), 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 C-6, the singlet scattering length a(S), and the tripler scattering length a(T).
