【摘要】 对Ａ≈１９０区超变形转动带分别用Ｈａｒｒｉｓ二参数公式和ａｂ公式进行了系统分析．分析结果表明，与正常变形核动带的情况相似，Ｈａｒｒｉｓ公式与实验有明显的系统偏离，而ａｂ公式则与实验很接近，可以相当精确和方便地描述超变形转动带．更多还原

【Abstract】 The superdeformed rotational bands in the A≈190 region are systematically analyzed using the Harris two-parameter formula and the ab expression, respeclively. Similar to the situations in normally deformed nuclei, there exist obvious and systematic deviation of Harris formula from the experiments, In contrast, the prediction of ab formula is very close to experiments, and can be conveniently used for the description of nuclear superdeformed bands.更多还原
