Abstract：
By the intrinsic condensate method,an attemption is made to cancel the maximum F-spintruncation approximation usually adopted in IBM2.In the region of deformed nuclei,the intrinsic condensate and is intrinsic excitations are used to describe the low-lying collective rotational states.Using this method.the low-luing spectrum of ¹⁶⁸Er are calculated.The result show that the maximum F-spin truncation approximation become bad for the excitational bands,and the intrinsic excitations of neutron boson and proton boson are mutual separated.
