    "abstract": "We study three-body recombination in an optically trapped ultracold gas of\ncesium atoms with precise magnetic control of the s-wave scattering length a.\nAt large positive values of a, we measure the dependence of the rate\ncoefficient on a and confirm the theoretically predicted scaling proportional\nto a^4. Evidence of recombination heating indicates the formation of very\nweakly bound molecules in the last bound energy level.",
