转动谱两参数和三参数公式的比较研究

A Comparing Analysis for Two-Parameter and Three-parameter Formula for Rotational Spectra

利用锕系偶偶核基带转动谱的实验数据，对两参数ａｂ公式用线性拟合的方法进行计算，并与非线性拟合进行比较。结果表明，对ａｂ公式，线性拟合也不失为一种较好的方法。计算结果还表明，吴－－曾提出的三种不同形式的三参数公式所得的结果相差不大，但都较ａｂ公式的计算结果更符合实验事实。

The two-parameter fits are both obtained with the method of linefit and nonlinefit by using the experimental date of the ground rotational bands of actinide even-even nuclei. The linefit of two-parameter formula is found a good method by analyzing their results. Wu-Zeng's three kinds of three-parameter formula are nonlinefited.Their results are nearly the same ,however, they are all better than the two-parameter fits'comparing to the experimental data.
