    "abstract": "We have analyzed the statistical distribution of the fluorescence signal\nlevels in a magneto-optical trap containing a few atoms and observed that it\nstrongly depends on the relative size of the bin time with respect to the trap\ndecay time. We derived analytic expressions for the signal distributions in two\nlimiting cases, long and short bin time limits, and found good agreement with\nnumerical simulations performed regardless of the size of the bin time. We\nfound an optimal size of the bin time for minimizing the probability of\nindeterminate atom numbers while providing accurate information on the\ninstantaneous number of atoms in the trap. These theoretical results are\ncompared with actual experimental data. We observed super-Poisson counting\nstatistics for the fluorescence from trapped atoms, which might be attributed\nto uncorrelated motion of trapped atoms in the inhomogeneous magnetic field in\nthe trap.",
