根据SATIF-6的结果，日本工作组对问题进行了修订，并将其发送给本行动的参与者进行重新计算。为了确定它们的能量依赖性，然后添加50和100 GeV的中子作为源中子。增加了24 GeV质子轰击Hg靶产生的90°次级中子谱作为次级中子源。其目的是确定次级中子的衰减长度对它们的谱的依赖性。本文对铁和混凝土的中子衰减长度进行了比较。评审的结果包括最近（2004年4月）由三个小组提交给主办机构的结果，以及在以前的SATIF会议上提交的结果。本文还讨论了从这一比较中引发的主题，这应该在未来进行调查。
Based on results presented at SATIF-6, problems were revised and sent by the Japanese Working Group to the participants of this action for re-calculation. To determine their energy dependence, 50 and 100 GeV neutrons were then added as the source neutrons. The secondary neutron spectrum for 90°, which was produced by 24 GeV protons on an Hg target, was added as the secondary neutron source. The purpose was to determine the dependence of the attenuation length of secondary neutrons on their spectra. This paper presents a comparison of the neutron attenuation length of iron and concrete. Results reviewed include those recently (April 2004) sent by three groups to the organiser and those presented at previous SATIF meetings. The paper also discusses themes evoked from this comparison, which should be investigated in the future.
