Description of superdeformed nuclei in the interacting boson model.


The interacting boson model is extended to describe the spectroscopy of superdeformed bands. Microscopic structure of the model in the second minimum is discussed and superdeformed bosons are introduced as the new building blocks. Solutions of a quadrupole Hamiltonian are implemented through the 1=N expansion method. E ects of the quadrupole parameters on… (More)
