Study on cross-section measurements has been promoted for $^{135}$ Cs among long-lived fission products in ImPACT Project. The feasibility study on $^{79}$ Se sample preparation also has been conducted to measure its cross sections in future. During the feasibility study, we started the neutron-capture cross-section measurements of stable Se isotopes. This paper reports research progresses on preparation of a radioactive $^{135}$ Cs sample, neutron irradiation experiments with the Cs sample, and cross-section measurements of stable Se isotopes.
