In this study, the natIn(g, nx) reaction cross sections were measured with the 63 MeV bremsstrahlung. The experiments were performed at the 100 MeV electron linac facility of the Pohang Accelerator Laboratory (PAL), Korea. Natural indium foils with a thickness of 0.1 mm and weight 0.08 g (isotope composition: In-113 4.3%, In-115 95.7%) were irradiated with the bremsstrahlung end-point energy of 63 MeV for 30 mins. Gold and aluminum foils with the thickness of 0.1 mm were used to evaluate the number of incident photons. The gamma rays emitted from the target after irradiation were measured using an HPGe detector connected to a PC based 4096 channel analyzer. Obtained averaged cross sections for the natIn(g, nx)In-110,111 reactions were compared with the theoretically calculated values based on TALYS 1.6 code. In this talk, we will report the experiment and analysis. This presentation was partly reported in Atomic Energy Society Japan 2018 Spring meeting [3].
