摘　　要：利用Bohr-Mottelson的I(I+1)展开三参数公式拟合能谱所定出的展开系数,计算130区和150区的超形变带的带首转动惯量。计算结果显出:它们的带着转动惯量没有表现出明显的奇偶差,说明130区和150区的原子核内对关联很弱。The transition spectra of superdeformed bands in A-130 and A-150 regions are fitted using three-parameter formula of Bohr-Mottelson's I(I+1) expansion,the coefficients are deteermined ,then moments of intertia of band are calcuated out.The results show that there is not obvious Odd-Even difference of bandhead moment of inertia of nuclear superdeformed states, we can conclude that nuclear pairing correlation in A-150 regions isn't important.
