Title: Collisional relaxation of Feshbach molecules and three-body recombination in {sup 87}Rb Bose-Einstein condensates

Abstract

We predict the resonance-enhanced magnetic field dependence of atom-dimer relaxation and three-body recombination rates in a {sup 87}Rb Bose-Einstein condensate close to 1007 G. Our exact treatments of three-particle scattering explicitly include the dependence of the interactions on the atomic Zeeman levels. The Feshbach resonance distorts the entire diatomic energy spectrum, causing interferences in both loss phenomena. Our two independent experiments confirm the predicted recombination loss over a range of rate constants that spans four orders of magnitude.
