摘要：
The mass-number dependence of the moment of inertia obtained from the energy difference between the ground state and the first 2+ state is studied in relation with the boson number in the SU (3) limit of the interacting boson model 1 (IBM-1). The analytic formula in the limit indicates that the pairing correlation between nucleons is directly related to the moment of inertia in the IBM. It is shown that the kinks of the moment of inertia of the Yb and Hf isotopes coincide exactly with the maximum boson numbers of each kind of isotopes. © 1990.
