摘要
Using axially-symmetric and triaxial superdeformed modelsπ[6001/2]band in 165Lu is investigated.The observedγ-transition energies can be reproduced quite well in both models.However,the triaxiality factor F(I)and the ratio of dynamical quadrupole moment Q(l)to Q(2)in axially-symmetric superdeformed model are essentially different from those in triaxial superdeformed model,which may be used to determine the nuclear shape.Precise measurement of the electromagnetic transition probabilities,combined with the information from the energy levels is necessary.Experimental information which may differentiate triaxial superdeformation from axially-symmetric superdeformation is discussed.
