Abstract
The Equation of Motion Method is used in the spectral analysis of a non self-adjoint bosonic Hamiltonian acting on an infinite dimensional Hilbert space. The presented operator has real eigenvalues and can be diagonalized when it is expressed in terms of pseudo-bosons , which do not behave as ordinary bosons under the adjoint transformation, but obey the Weil-Heisenberg commutation relations.
