Abstract: The measurements of fine-structure changing collisions in a cesium magneto-optical trap, rp ported in a previous work [A. Fioretti et al., Phys. Rev. A 55, R3999 (1997)], are reanalyzed within a model based on the flux enhancement effect, which takes place in cold atomic collisions. In the present analysis, we consider the cooperative effect of the long-range and the shorter-range excitation by the strong trap laser. We evidence also the important role of the hyperfine structure of the Cs-2 molecular levels asymptotically connected to the 6S(1/2) + 6S(1/2) ground-state and 6S(1/2) + 6P(3/2) excited-state dissociation limits.
