Abstract- In this paper we present a general theoretical model for the interaction of a number of two-level atoms in

Bose-Einstein condensate (BEC) with a single-mode quantized field. In addition to the usual interacting terms, the Hamiltonian of system contains interatom as well as higher-order atom-field interactions. To  quantify the spontaneous emission, we obtain analytical expressions for  atomic population inversion (API), in the cases of number and coherent states

for atomic subsystem. Our results show that the above-mentioned model interaction leads to the appearance of collapse-revival phenomenon in API. Also, the revival time may be tuned by adjusting the interatom interaction constant.

Keywords: Keywords: Spontaneous emission, collapse-revival, squeezing, Bose-Einstein condensate, atomic population inversion.
