Under the ImPACT project, the neutron capture cross-section measurements of Cs-135 among the long-lived fission products have been performed at J-PARC and Kyoto University. In this presentation, the measurenments ofenergy-dependent neutron capture cross-section for Cs-135 will be reported, and the neutron irradiations of Cs-135 at the KUR will be also presented.
