用中子源反应测量了15-21 MeV中子能范围内的和截面。这些数据旨在为解释所谓的飞行中反应中子产额提供一个准确的数据库，这为研究劳伦斯利弗莫尔国家实验室国家点火设施中惯性约束聚变激光发射中产生的氚-氚等离子体的性质提供了一个灵敏的工具。将这些数据与以前对所研究的反应的数据和评价进行了比较，发现它们与ENDF/B-VIII.0的评价很好地吻合，尽管对反应进行了小幅调整。到目前为止，在任何截面测量中，同一小组首次获得了从阈值到21 MeV的全面数据集。
Theandcross sections have been measured in the neutron energy range between 15 and 21 MeV using theneutron source reaction. Thedata are intended to provide an accurate database for interpreting so-called reaction-in-flight neutron yields, which provide a sensitive tool for studying properties of the deuterium-tritium plasma created in inertial confinement fusion laser shots at the National Ignition Facility at Lawrence Livermore National Laboratory. The data are compared to previous data and evaluations for the reaction studied and are found to be in good agreement with the ENDF/B-VIII.0 evaluation, although small adjustments are necessary for thereaction. For the first time in anycross-section measurements to date, a comprehensive data set ranging from threshold to 21 MeV has been obtained by the same group.
