用I(I+1)展开式分析超形变带

ANALYSIS ON SUPERDEFORMED BANDS BY USING I(I +1) EXPANSION

用ＢｏｈｒＭｏｔｅｌｓｏｎＩ（Ｉ＋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）的理论计算值能较好地符合实验提取值；Ａ～１９０区超形变带的四参数数值关系并不支持Ｈａｒｉｓ公式及ａｂ公式的理论预期值，但相对而言。

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.
