    "abstract": "We study elastic collisions in an optically trapped spin mixture of fermionic\nlithium atoms in the presence of magnetic fields up to 1.5kG by measuring\nevaporative loss. Our experiments confirm the expected magnetic tunability of\nthe scattering length by showing the main features of elastic scattering\naccording to recent calculations. We measure the zero crossing of the\nscattering length that is associated with a predicted Feshbach resonance at\n530(3)G. Beyond the resonance we observe the expected large cross section in\nthe triplet scattering regime.",
