【摘要】 利用Bohr-Mottelson的I(I+1 )四参数展开式分析了A～ 1 5 0 ,1 90偶偶核超形变带和锕系、稀土区偶偶核正常形变转动带。由最小二乘法拟合计算出参数 ,讨论参数之间的关系 ,发现ab公式、abc公式和Harris公式的预言存在不同程度的偏离。但相对而言 ,ab公式、abc公式的预言较好。而且超形变带的参数关系和正常形变带相似更多还原

【Abstract】 Using four-parameter Bohr-Mottelson formula,we analyze some ground rotational bands of even-even nuclei.The nuclei include superdeformed(SD) nuclei in A～150 、190 regions and normal deformed(ND) nuclei in actinide and rare-earth.The parameters obtained by the least-square fitting deviate from the relations derived from ab formula ,abc formula and abc formula,but are closer to relations deduced from ab formula and abc formula.Additionally,the relations to parameters of SD bands are similar to those of ND bands.更多还原
