Abstract:
In order to investigate some approximations involved in the generalized semimicroscopic model (GSMM), a cluster-phonon model is presented in which a hole or two holes and one particle are coupled between them through Q-Q plus pairing interactions, and to the quadrupole vibrations of a doubly even core having a closed shell. Anharmonicities are also included phenomenologically. Matrix elements are computed using graphical methods and nunumerical calculations are performed for Co57 and In115, selected as well known examples of odd-mass nuclei in the 1f72 and 1g92 shells, respectively. A good fit to energy levels is achieved through a reasonable variation of the model parameters, and the predictions of the GSMM about the nature of the low-lying levels in both nuclei are confirmed. The calculated electromagnetic properties and spectroscopic factors compare favorably with experiment except for some discrepancies in In115.
