Direct Observation of Sub-Poissonian Number Statistics in a Degenerate   Bose Gas
  We report the direct observation of sub-Poissonian number fluctuation for a degenerate Bose gas confined in an optical trap. Reduction of number fluctuations below the Poissonian limit is observed for average numbers that range from 300 to 60 atoms.
