Measurements of the Ag-107 neutron capture cross sections with pulse height weighting technique at the CSNS Back-n facility

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 Ag-107 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 Ag-107 is required. Meanwhile, Ag-107 is also an important weak r nucleus. Thus, the cross sections for neutron induced interactions with Ag-107 are very important both in nuclear energy and nuclear astrophysics. The (n, y) cross section of Ag-107 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 Ag-107 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.
