对“中子强度函数极大值附近核的部分中子宽度分布”一文的评论

Comment on "Distribution of Partial Neutron Widths for Nuclei Close to a Maximum of the Neutron Strength Function"

P. E. Koehler, F. Bečvář, M. Krtička, J. A. Harvey, K. H. Guber

摘要:

最近的一封信试图调和中子共振数据和随机矩阵理论(RMT)之间的分歧。为此,导出了一个新的公式,将测量的中子宽度(Γ_{λn})转换为s波共振(λ= 1,2,.)的约化中子宽度(Γ_{λn}^0)。在s波中子强度函数的峰值附近的核素中。在这篇评论中,我们表明,这种重新标度一般不会被期望调和所观察到的分歧类型,并证明它确实不适用于所讨论的特定情况。因此,RMT和这些数据之间的分歧仍然存在。

英文摘要:

A recent Letter attempted to reconcile the disagreement between neutron resonance data and random matrix theory (RMT). To this end, a new formula was derived for transforming measured (Γ_{λn}) to reduced (Γ_{λn}^0) neutron widths for s-wave resonances (λ=1,2,...) in nuclides near peaks of the s-wave neutron strength function. In this Comment, we show that such a rescaling would not, in general, be expected to reconcile the type of disagreement observed, and demonstrate that indeed it does not for the specific cases in question. Hence, the disagreements between RMT and these data remain.
