英文摘要:
The extended interacting boson model with s-, p-, d-, f- and g-bosons included (spdfg IBM) is investigated. The algebraic structure including the generators, the Casimir operators of the groups at the SU(5) dynamical symmetry and the branching rules of the irreducible representation reductions along the group chain are obtained. The typical energy spectrum of the symmetry is given.
