Abstract: The results of recent photoionization experiments performed on laser cooled cesium and rubidium atoms are critically examined. The role of processes, as ion diffusion and recombination, determining the time evolution and the rate of the produced atomic ions is discussed. A more precise model of the ion evolution is presented, numerically solved and compared to the experimental data. (C) 2000 Elsevier Science B.V. All rights reserved.
