摘要

为了确定放射性原子核的中子俘获率,我们开发了一种使用替代反应的实验技术,特别是逆运动学中的(d, p)反应。通过识别出的反应残基来推导出非束缚态的γ发射概率,而不是检测来自化合物态的去激发γ射线。通过使用能够使光束减速和聚焦的OEDO装置和RIBF的SHARAQ光谱仪,这样的实验变得可行。我们应用该技术测量了79Se的中子俘获率,用于核嬗变数据,以及130Sn的中子俘获率,用于r过程相关的研究。在这篇文章中,我们用替代比值法讨论了79Se的中子捕获截面,并介绍了130Sn测量的最新实验装置。

The surrogate reactions for the neutron-capture rate using OEDO and SHARAQ in RIBF
To determine the neutron capture rates of radioactive nuclei, we have developed an experimental technique using surrogate reactions, specifically the (d, p) reaction in inverse kinematics. The gamma-emission probabilities from unbound states were deduced by identifying the outgoing reaction residues, instead of detecting the de-excitation γ rays from the compound states. Such experiments have become feasible through the use of the OEDO device, which enables beam deceleration and focusing, and the SHARAQ spectrometer at RIBF. We applied this technique to measure the neutron capture rates of 79Se for nuclear transmutation data, and of 130Sn for studies related to the r-process. In this contribution, we discuss the neutron-capture cross sections of 79Se using the surrogate ratio method, and introduce the updated experimental setup for the 130Sn measurement.
