偶偶核Yrast能量经验公式中的转动能项

Rotational energy term in the empirical formula for the yrast energies in even-even nuclei

Eunja Ha, S. W. Hong

摘要:

我们证明了描述偶偶核自然宇称偶多极态yrast能量测量总体特征的经验公式的一部分可以与核的转动能联系起来。当经验公式的第一项$αA^{-γ}$被视为转动能时,我们可以更好地理解前面对激发能的分析结果。我们表明,通过考虑$αA^{-γ}$项作为刚性转子的旋转能量新获得的参数$α$和$γ$的值与从早期的“修改的”$χ^2$分析中提取的那些值是非常一致的,在该分析中,我们使用激发能的矩阵来定义“修改的”$χ^2$值。

英文摘要:

We show that part of the empirical formula describing the gross features of the measured yrast energies of the natural parity even multipole states for even-even nuclei can be related to the rotational energy of nuclei. When the first term of the empirical formula, $αA^{-γ}$, is regarded as the otational energy, we can better understand the results of the previous analyses of the excitation energies. We show that the values of the parameters $α$ and $γ$ newly obtained by considering the $αA^{-γ}$ term as the rotational energy of a rigid rotor are remarkably consistent with those values extracted from the earlier `modified' $χ^2$ analyses, in which we use the logarithms of the excitation energies in defining the `modified' $χ^2$ values.
