    "abstract": "The resonant interaction of two nonidentical two-level atoms with one mode of\nthe electromagnetic field has been considered. The pure-state evolution of the\natomic states for field initially in the coherent state and atoms in the ground\nstate has been investigated. It has been shown that for intermediate values of\nthe relative differences of two coupling constants the atoms as well as the\nfield are returned most closely to a pure state at the revival time. The\npossibility of the maximally entangled states at the beginning of the collapse\ntime has been discussed.",
