  We study the resonance interaction between two entangled identical atoms
coupled to a quantized scalar field vacuum, and accelerating between two
mirrors. We show how radiative processes of the two-atom entangled state can be
manipulated by the atomic configuration undergoing noninertial motion.
Incorporating the Heisenberg picture with symmetric operator ordering, the
vacuum fluctuation and the self-reaction contributions are distinguished. We
evaluate the resonance energy shift and the relaxation rate of energy of the
two atom system from the self-reaction contribution in the Heisenberg equation
of motion. We investigate the variation of these two quantities with relevant
parameters such as atomic acceleration, interatomic distance and position with
respect to the boundaries. We show that both the energy level shift and the
relaxation rate can be controlled by tuning the above parameters.
