2022-04-22 Measurement of 232Th (n,γ) cross section at the CSNS Back-n facility in the unresolved resonance region from 4 keV to 100 keV doi:10.11922/sciencedb.j00113.00015 en The data related to the article "Measurement of 232Th (n,γ) cross section at the CSNS Back-n facility in the unresolved resonance region from 4 keV to 100 keV" submitted to the journal of Chinese Physics B. The neutron capture cross section of 232Th was measured at the neutron time-of-flight facility Back-n of China Spallation Neutron Source (CSNS) for the first time. The measurement was performed with 4 hydrogen-free deuterated benzene C6D6 liquid scintillation detectors, in the ES#2 experiment station on the beam line, at a distance of about 76 m from the neutron-production assembly. The total energy detection principle in combination with the Pulse Height Weighting Technique (PHWT) was applied to analyze the measured data. Results of the 232Th (n,γ) reaction cross section in the unresolved resonance region from 4 keV to 100 keV are obtained, which shows a good agreement with the existing experimental data from EXFOR, as well as with the evaluated data from the ENDF/B-VIII.0 and CENDL-3.1. In addition, the excitation function of 232Th (n,γ)233Th reaction in the unresolved resonance region was theoretically calculated by using the code TALYS-1.95. The data files consists of 2 separate Excel files, which are obtained from the analysis results of experimental data, the related simulation results, and the public databases ENDF/B VIII-0, CENDL-3.1, and EXFOR. The details are described as follows: Cross_sec.xlsx : Energy-cross section data from present measurement, the public EXFOR database, ENDF/B-VIII.0 database, CENDL-3.1 database, and TALYS calculation.Detector_eff.xlsx : Simulation results of the C6D6 detector efficiency from GEANT4 tookit.
