The GIBM version, which includes all sixth-order terms in the expansion of the collective part of the NN-potential, has been obtained. This GIBM Hamiltonian contains additional terms compared with the standard (sd-boson) interacting boson model (IBM). The microscopic expressions for the standard IBM Hamiltonian parameters in terms of the employed effective NN-potential parameters have also been obtained.331-349engMicroscopic generalization of the standard interacting boson model Hamiltonian in the restricted dynamics approachArtigo10.1088/0954-3899/22/3/007WOS:A1996UA49200007Acesso restrito
