Measurements of the 107Ag neutron capture cross sections with PHWT at the CSNS Back-n facility

The data related to the article "Measurements of the 107Ag neutron capture cross sections with PHWT at the CSNS Back-n facility" published in the journal Chinese Physics B. Silver indium cadmium (Ag-In-Cd) control rod is widely used in pressurized water reactor nuclear power plants, which is continuously consumed in a high neutron flux environment. The mass ratio of 107Ag in Ag-In-Cd control rod is 41.44%. To accurately calculate the consumption value of the control rod, a reliable neutron reaction cross section of the 107Ag is required. Meanwhile, 107Ag is also an important weak r nuclei. Thus, the cross sections for neutron induced interactions with 107Ag are very important both in nuclear energy and nuclear astrophysics. In this study, the (n,γ) cross section of 107Ag has been measured in the energy range of 1–60 eV using a back streaming white neutron beam line at China spallation neutron source. The resonance parameters are extracted by an R-matrix code. It contains 3 Excel files, which are described below：cross seection.xlsx : experimental data of neutron capture cross section of 107Ag between 1 and 60 eV.Resonance Parameters(Ag-109).xlsx : resonance parameters of 109Ag extracted by R-matrix from experimental data.Resonance Parameters(Ag-107).xlsx : resonance parameters of 107Ag extracted by R-matrix from experimental data.本数据集关联发表于《中国物理B》（Chinese Physics B）的论文《利用中国散裂中子源（China Spallation Neutron Source, CSNS）Back-n束线的PHWT测量107Ag中子俘获截面》（原文英文标题："Measurements of the 107Ag neutron capture cross sections with PHWT at the CSNS Back-n facility"）。银铟镉（Ag-In-Cd）控制棒广泛应用于压水堆核电站，在高中子通量环境下持续发生消耗，其中107Ag在该类控制棒中的质量占比为41.44%。为精准计算控制棒的消耗值，需获取可靠的107Ag中子反应截面数据。同时，107Ag亦是重要的弱r过程核素（weak r nuclei），因此107Ag与中子的诱发反应截面在核能领域与核天体物理领域均具有关键价值。本研究依托中国散裂中子源背向流白中子束线，在1–60 eV能区完成了107Ag的(n,γ)俘获截面测量，并通过R矩阵（R-matrix）程序提取了共振参数。本数据集包含3个Excel文件，具体说明如下： 1. cross section.xlsx：1–60 eV能区107Ag中子俘获截面的实验测量数据 2.
