Abstract We propose a new method for the energy eigenvalue problem for boson systems with either weak or strong two-body interactions. It is also shown that this method is particularly simple and effective to obtain the explicit analytical expressions of energy eigenvalues and eigen-states for interacting harmonic oscillators especially when the number of the oscillators is huge.
