Maximal entanglement between the atom and its spontaneous emission field is generated just by the rates of incoherent pumping fields. The effect of quantum interferences arising from incoherent pumping processes and spontaneous emission fields (decay induced interference) on atom-photon entanglement is discussed. The maximum atom-photon entanglement establishes when the population almost equally distributes among the bare states. No laser fields are used at any stage of the processes.
