In order to simplify the complicated sdg interacting boson model (IBM) Hamiltonian, a microscopic approach based on the Dyson boson mapping and the MJS substitution was presented, and the leading terms in the interaction Hamiltonian were discussed by using numerical investigation. Comparisons of both the calculated levels and the overlap of wave functions between the exact results and the approximations were made to find out negligible part in the Hamiltonian. The results show that the leading terms determined in this paper may provide a way...

Starting from one of the microscopic sdg interacting boson approximations, the lead-ing terms in the interaction Hamiltonian are discussed by using numerical investigations. Com-parisons of both the calculated levels and the overlap of wave functions between the exact re-sults and the approximations are made to find out negligible part in the Hamiltonian. The re-sults show that the leading terms given in this paper may provi...
