对“超冷中子在钆中的巨吸收截面”一文的评论

Comment on "Giant absorption cross section of ultracold neutrons in Gadolinium"

J. Felber, R. Gaehler, R. Golub

摘要:

Rauch等人(PRL 83,4955,1999)比较了他们对超冷中子Gd截面的测量和对热中子截面的外推,并从中子的相干性质方面解释了这种差异。我们表明,使用的外推是基于一个误解,相干性在吸收中不起作用。

英文摘要:

Rauch et al (PRL 83, 4955, 1999) have compared their measurements of the Gd cross section for Ultra-cold neutrons with an exptrapolation of the cross section for thermal neutrons and interpreted the discrepancy in terms of coherence properties of the neutron. We show the extrapolation used is based on a misunderstanding and that coherence properties play no role in absorption.
