    "abstract": "We have found that, in the intensity-dependent Jaynes-Cummings model, a field\ninitially prepared in a statistical mixture of two coherent states, $|\\alpha\u003e$\nand $|-\\alpha\u003e$, evolves toward a pure state. We have also shown that an\neven-coherent state turns periodically a into rotated odd-coherent state during\nthe evolution.",
