    "abstract": "We have experimentally explored a novel possibility to study exoergic cold\natomic collisions. Trapping of small countable atom numbers in a shallow\nmagneto-optical trap and monitoring of their temporal dynamics allows us to\ndirectly observe isolated two-body atomic collisions and provides detailed\ninformation on loss statistics. A substantial fraction of such cold collisional\nevents has been found to result in the loss of one atom only. We have also\nobserved for the first time a strong optical suppression of ground-state\nhyperfine-changing collisions in the trap by its repump laser field.",
