The dynamical properties in the system of three identical two-level entangled atoms interacting with the Fock states field are investigated by mean of Schr?dinger equation solution and numerical calculations. The results show that the time evolution of the atomic popula-tion operator and second order coherence degree depend on the degree of entanglement of the entangled atoms and the intensity of the Fock states optical field. If the two atoms are in un-entangled state,the atomic population reveals the periodic collapse and revival phenomenon.The atomic population reveals vacuum Rabi oscillation when the optical field is in vacuum state,and the Rabi oscillation frequency of the atomic population is shown to increase with the growth of the intensity of the optical field. If the two atoms are in entangled state,the photon reveals the bunching phenomenon with the growth of the degree of the entangled state,and the second-order correlation function is shown to increase with the growth of the degree of the entangled state.
