摘要
改进了从γ跃迁能量中扣除振荡起伏部分的方法．在此基础上，采用ab公式或改进的ab公式，系统地讨论了A≈190区奇A核中的超形变带，给出了绝大多数超形变带的自旋值．部分超形变带的自旋指定值不同于其它方法得到的结果．
The influence of the I= 1 staggering and the fluctuation in observed γ-tyanstion energies on the spin assignments of superdeformed bands is taken into account properly. An improved approach for removing the fluctuations from the observed y transition energies is proposed. The smoothed transition energies are fitted by the ah expression or its modification to assign the spins of the superdeformed bands in the odd-A nuclei in A =190 region. The assigned spins for some superdeformed bands are different from those given in other approaches.
