    "abstract": "Cold inelastic collisions between confined cesium (Cs) atoms and Cs$\\_2$\nmolecules are investigated inside a CO$\\_2$ laser dipole trap. Inelastic\natom-molecule collisions can be observed and measured with a rate coefficient\nof $\\sim 2.5 \\times 10^{-11} $cm$^3$ s$^{-1}$, mainly independent of the\nmolecular ro-vibrational state populated. Lifetimes of purely atomic and\nmolecular samples are essentially limited by rest gas collisions. The pure\nmolecular trap lifetime ranges 0,3-1 s, four times smaller than the atomic one,\nas is also observed in a pure magnetic trap. We give an estimation of the\ninelastic molecule-molecule collision rate to be $\\sim 10^{-11}$ cm$^{3}$\ns$^{-1}$.",
