Phys. Rev. A 69, 032705 (2004) [4 pages]Measurement of a mixed-spin-channel Feshbach resonance in 87RbReceived 12 September 2003; revised 10 November 2003; published 16 March 2004 We report on the observation of a mixed-spin-channel Feshbach resonance at the low magnetic field value of 9.09±0.01 G for a mixture of ∣2,−1⟩ and ∣1,+1⟩ states in 87Rb. This mixture is important for applications of multicomponent Bose-Einstein condensates of 87Rb, e.g., in spin mixture physics and for quantum entanglement. Values for position, height, and width of the resonance are reported and compared to a recent theoretical calculation of this resonance. © 2004 The American Physical Society URL:
