    "abstract": "We present first indications of sympathetic cooling between two neutral,\noptically trapped atomic species. Lithium and cesium atoms are simultaneously\nstored in an optical dipole trap formed by the focus of a CO$_2$ laser, and\nallowed to interact for a given period of time. The temperature of the lithium\ngas is found to decrease when in thermal contact with cold cesium. The\ntimescale of thermalization yields an estimate for the Li-Cs cross-section.",
