Energy spectrum inverse problem was investigated in our previous work [1] using the connection between q-deformed harmonic oscillator and Morse-like aharmonic potential. We have proposed deformed-three-levels simple model, where the set-parameters of Morse potential and the corresponding set-parameters of level deformations are easily and explicitly defined. In this work, using this deformed-three-levels simple model we study the entanglement in composite bosons. Introducing the definition of relative entanglement (differential) entropy for composite bosons, we study the deformation of energy levels of a single boson when the surrounding environment effect was taken into account. Like the case of Fucault pendulum in experimental demonstration the rotation of the Earth, our deformation energy level investigation might be useful in detecting entanglement information of the system in a closed box and outside environment. Some application examples of our model are considered.
