| 摘 要： | 用Bohr－MottelsonI（＋1）展开四参数转动谱公式系统分析了A～190、150区的超形变转动带．结果表明：四参数ABCD公式能够相当好地描述上述两个区的超形变带，若干核第二类转动惯量J(2)的理论计算值与实验提取值符合较好；A～190区超形变带的四参数数值关系并不支持Harris公式及ab公式的理论预期值，但相对而言，ab公式的理论预期值与实验提取值更为接近．

| Abstract: | The superdeformed bands in the A-190 and 150 regions are systematically analyzed using four-parameter rotational spectra formula of Bohr-Mottelson's I(I+1) expansion. The result shows that the superdeformed bands in the A-190 and 150 regions can be described very well with four-parameter ABCD-formula. The theoretical values of J(2) of most of nuclei accord with the experimental extracted values. The four-parameter value relation doesn' t support the theoretical expected values of ab and Harris formula, but comparatively the theoretical expected value of ab formula agrees with the experimental extracted values better than that of Harris formula. |
