Abstract
Antibunching and sub-Poissonian statistics of the 11-μm photon emission from the to transition in one and two trapped ions have been inferred from the quantum jumps of the laser-induced fluorescence of the first resonance transition at 194 nm. Each downward step in fluorescence was assumed to mark the emission of an 11-μm photon. Signals from two ions were consistent with the assumption that quantum jumps in the two ions occurred independently. Mandel's parameter was determined to be approximately -0.25 for one and two ions.
