Abstract

We study three-body recombination in an optically trapped ultracold gas of cesium atoms with precise magnetic control of the s-wave scattering length a. At large positive values of a, we measure the dependence of the rate coefficient on a and confirm the theoretically predicted scaling proportional to a4. Evidence of recombination heating indicates the formation of very weakly bound molecules in the last bound energy level.
