摘　　要：Similar band structure has been found in odd-odd nucleus 104, 106, 108Ag[1-3], 108, 110In[4] and 102Rh[5] in A^110 mass region, they are all magnetic dipole bands. Their dynamic moment of inertia (J(2)) areSimilar band structure has been found in odd-odd nucleus ^104, 106,108Ag^[1-3], 108, 110in^[4] and ^102Rh^[5] in A-110 mass region, they are all magnetic dipole bands. Their dynamic moment of inertia （J^（2）） are smaller than the normal deformed band, such as band 4 in ^130Ba^[6], and even smaller than the super deformed band, in ^152Dy^[7], as shown in Fig. 1. The configuration of these dipole bands in ^104, 106Ag, ^108, 110in has been reported as πg9/2×v[h^211/2（g7/2/d5/2）] respectively. The level structure and de-excite pathways of the band 6 built on 12＋h state in ^108Ag^[3] are very similar. The maximum angular momentum of band 6 in ^108Ag observed in the experiment is 17h, this is consistent with the maximum angular momentum provided by the configuration of πg9/2×v[h^211/2（g7/2/d5/2）], these characters all suggest that band 6 in ^108Ag probably has the same configuration as band 1 in ^106Ag.
