A cesium magneto-optical trap operating at a large atomic density in m
ultiple scattering regime has been investigated The trap operates with
a large Rabi frequency for trapping lasers, The atomic number, the di
mension of the atomic cloud, the atomic density, and the atomic temper
ature have been measured as a function of trap parameters. At differen
t trap conditions, the product of the atomic number and of the atomic
density, which determines the occurrence of collisional processes, has
been also examined. Our results are interpreted on the basis of laser
cooling processes.
