Abstract
Silver indium cadmium (Ag–In–Cd) control rod is widely used in pressurized water reactor nuclear power plants, and it is continuously consumed in a high neutron flux environment. The mass ratio of 107 Ag in the 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 107 Ag is required. Meanwhile, 107 Ag is also an important weak r nucleus. Thus, the cross sections for neutron induced interactions with 107 Ag are very important both in nuclear energy and nuclear astrophysics. The (n, γ ) cross section of 107 Ag 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. All the cross section of 107 Ag and resonance parameters are given in this paper as datasets. The datasets are openly available at http://www.doi.org/10.11922/sciencedb.j00113.00010 .
