The cross section for Sn reaction has been measured in the neutron energy from 1eV to 1keV using the ANNRI-NaI(Tl) spectrometer at J-PARC/MLF. The sample used in the present experiment was metal tin enriched in Sn by 87%. The impurities of Sn and Sn were 9.3% and 3%, respectively. In the data analysis, the background of the frame-overlap neutrons and the scattered neutrons were subtracted. Comparison with the evaluation of JENDL-4.0 and ENDF/B-VII.1 will be presented in the poster session.
