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.
