Abstract：
The IBM intrinsic ground-state,single phonon and double phonon excited-states are given,where the double phonon states are different linear combinations of single phonon states.The Hamiltonian is defined as both SU(3) limit and pairing interaction.Using cranking theory,the moment of inertia and energy spectrum for these states are calculated,and rational analytical expressions obtained.As an example,the rationality of these results is also discussed for ¹⁶⁸Er.
