Phys. Rev. Lett. 93, 143201 (2004) [4 pages]Three-Boson Problem near a Narrow Feshbach ResonanceReceived 2 April 2004; published 27 September 2004 We consider a three-boson system with resonant binary interactions and show that for sufficiently narrow resonances three-body observables depend only on the resonance width and the scattering length. The effect of narrow resonances is qualitatively different from that of wide resonances revealing novel physics of three-body collisions. We calculate the rate of three-body recombination to a weakly bound level and the atom-dimer scattering length and discuss implications for experiments on Bose-Einstein condensates and atom-molecule mixtures near Feshbach resonances. © 2004 The American Physical Society URL:
