| 摘 要： | In this paper we study collective motion under random two-body interactions in the fermion dynamical symmetry Model (FDSM). It is found that a Hamiltonian with the SO(8) symmetry of the FDSM does not give generic vibration and rotation under random interactions while that with the SP(6) symmetry does. |
| 关 键 词： | random interactions regular structure collective motion symmetry |
