An Investigation of G Pair Included Fermion Dynamical Symmetry Model for Medium and Heavy Mass Nuclei

  • A new description of the hexadecapole degree of freedom in the medium and heavy mass region in the framework of the Fermion Dynamical Symmetry Model (FDSM) is proposed.In this paper,the k-active case is discussed in detail,in which the pairing and multipole operators generate SP10 group.The energy spectra are derived for two limits of the pairing,quadrapole and hexadecapole strength.Finally,the spectra of 204Pb are fitted and compared with the experimental values and the results obtained from sdg IBM.

Abstract: A new description of the hexadecapole degree of freedom in the medium and heavy mass region in the framework of the Fermion Dynamical Symmetry Model (FDSM) is proposed.In this paper,the k-active case is discussed in detail,in which the pairing and multipole operators generate SP10 group.The energy spectra are derived for two limits of the pairing,quadrapole and hexadecapole strength.Finally,the spectra of 204Pb are fitted and compared with the experimental values and the results obtained from sdg IBM.
