    "abstract": "We show, both experimentally and theoretically, that sympathetic cooling of\n$^{87}$Rb atoms in the $|F=2,m_F=2\u003e$ state by evaporatively cooled atoms in the\n$|F=1,m_F=-1\u003e$ state can be precisely controlled to produce dual or single\ncondensate in either state. We also study the thermalization rate between two\nspecies. Our model renders a quantitative account of the observed role of the\noverlap between the two clouds and points out that sympathetic cooling becomes\ninefficient when the masses are very different. Our calculation also yields an\nanalytical expression of the thermalization rate for a single species.",
