In this paper we have studied the low energy structure of 115-119Sn isotopes within the vibrational limit for bosons under UBF(5)⊗SUF(4) dynamical symmetry of the graded Lie group U(6/20). Calculation of excitation energy spectra of positive parity levels and B(E2) values of these isotopes has been performed using this dynamical symmetry. Comparison of experimental and calculated energy spectra and B(E2) values of these nuclei suggests the existence of an approximate U(6/20) supersymmetry in these isotopes.

In this paper, the normal and the intruder 2p-2h bands in even [Formula Presented]Sn isotopes have been studied through configuration mixing calculation in the framework of IBM-2. The states belonging to the normal and the intruder bands have been calculated separately and then allowed to mix by using a simple band-mixing Hamiltonian. Energy values, [Formula Presented] transition probabilities, and quadrupole moments of the first 2[Formula Presented] state have been calculated and compared with the experimental values. © 1997 The American Physical Society.

Configuration mixing calculation in the framework of the interacting boson model (2) in even [Formula Presented]Sn isotopes

Supersymmetry calculations are performed for the Ni isotopes within the framework of the IBM using the concept of dynamic symmetries for the U(5)*SUF(2) limit of the graded Lie group U(6 mod 10). The excitation spectra and the electric quadrupole transitions of the isotopes belonging to the same representation of the graded Lie group and the spectroscopic factors for single-particle pick-up reactions between such isotopes are calculated and compared with experimentally observed values. The results are encouraging.
