摘要

放射性核的(n,γ)直接测量通常具有挑战性。大量的努力致力于发展间接技术和对天体物理学感兴趣的短寿命放射性核素进行测量。洛斯阿拉莫斯中子科学中心(LANSCE)正在探索一种新的间接技术,该技术可以从中子传输数据中计算平均神经元捕获特性。在过去两年中,LANSCE一直在调试一个中子传输站。放射性核素间接捕获实验装置(DICER)目前能够对直径小至1毫米、质量低至几毫克的稳定圆柱形样品进行测量。第一年的运行表明,DICER仪器已经准备好对放射性样品(88Zr, t1/2=83.4天)进行首次测量,计划于2021年冬季进行。简要介绍仪器和最新DICER结果的细节。

A new approach for indirect capture measurements: The DICER neutron transmission station at LANSCE
Direct (n,γ) measurements on radioactive nuclei can often be challenging. Substantial effort has been devoted to developing indirect techniques and perform measurements on short-lived radionuclides of astrophysical interest. A new indirect technique is being explored at the Los Alamos Neutron Science Center (LANSCE) which enables the calculation of average neuron capture properties from neutron transmission data. A station for neutron transmission, has been under commissioning during the last two years at LANSCE. The Device for Indirect Capture Experiments on Radionuclides  (DICER) is currently capable of carrying out measurements on stable cylindrical samples with a diameter as small as 1 mm and mass as low as a few mg. The first year of operation indicate that the DICER instrument is ready to perform its first measurement on a radioactive sample (88Zr, t1/2=83.4 days) which is planned for the winter of 2021. A brief description of the apparatus and details on the latest DICER results will be presented.
