标题： Commissioning of the BRIKEN detector for the measurement of very exotic beta-delayed neutron emitters

摘要： 一个新的探测系统已在日本理化学研究所西纳中心安装，用于研究非常富中子核的衰变特性。 该装置由三个主要部分组成：一个缓发中子计数器，一个对放射性离子的植入和衰变敏感的探测系统，以及伽马射线探测器。 本文描述了该装置、调试实验以及一些选定的结果，展示了其在测量半衰期和β延迟中子发射概率方面的性能。 详细描述了数据分析所采用的方法。 特别强调了对偶然中子背景的校正。 显示英文摘要

摘要： A new detection system has been installed at the RIKEN Nishina Center (Japan) to investigate decay properties of very neutron-rich nuclei. The setup consists of three main parts: a moderated neutron counter, a detection system sensitive to the implantation and decay of radioactive ions, and gamma-ray detectors. We describe here the setup, the commissioning experiment and some selected results demonstrating its performance for the measurement of half-lives and beta-delayed neutron emission probabilities. The methodology followed in the analysis of the data is described in detail. Particular emphasis is placed on the correction of the accidental neutron background.
