摘要：

The interaction of a two-level atom with a quantized cavity field in an even coherent state, defined as an eigenstate of a2: a2\z> = z\z>, is investigated. We find that for an initial integer average photon number, at the time of the first revival, the field nearly returns to an even coherent state but with z replaced by ze(ipi). Just before the revival, the field is found to be in an odd field state. At half the revival time it is in a mixed state showing larger scale oscillations in the photon number distribution.
