    "abstract": "We present the first simultaneous trapping of two different ultracold atomic\nspecies in a conservative trap. Lithium and cesium atoms are stored in an\noptical dipole trap formed by the focus of a CO$_2$ laser. Techniques for\nloading both species of atoms are discussed and observations of elastic and\ninelastic collisions between the two species are presented. A model for\nsympathetic cooling of two species with strongly different mass in the presence\nof slow evaporation is developed. From the observed Cs-induced evaporation of\nLi atoms we estimate a cross section for cold elastic Li-Cs collisions.",
