The measurements of fine-structure
changing collisions in a cesium magneto-optical
trap, reported 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 Cs2 molecular levels
asymptotically connected to the
ground-state and
excited-state dissociation limits.
