Neutron capture cross section of Indium on the s-process temperatures via Time-of-Flight at the CSNS Back-n facility

The detector efficiency was corrected using the pulse height weighting technique. The final cross sections fitted by the R-matrix codes match well with those given by the evaluation libraries ENDF/B-VIII.1, JEFF-3.3, JENDL-5 and TENDL-2023.

This study used the R-matrix code SAMMY to analyze neutron capture yields and extract resonance parameters from 1 eV to 2 keV. The TALYS code was used to describe the experiment results at the unresolved resonance region.
