As part of the ImPACT project, it is currently planned to measure the neutron cross-section of Cs (half-life y), a long-lived fission product (LLFP), via neutron time-of-flight (TOF) method using ANNRI in the Material and Life science Facility (MLF) at the Japan Proton Accelerator Research Complex (J-PARC). Cs (natural Cs, stable) exists as a contaminant in the Cs sample. To make an accurate measurement of Cs, accurate data of the Cs cross-section is required. We have measured the neutron cross-section in the thermal and epithermal energy regions. We will report on the measured cross-section data, resonances, and our methodology.

There is currently a plan to measure the neutron-capture cross-section of Cs (half-life 2.3 million years), using the neutron beam at the Materials and Life science Facility (MLF) at J-PARC. In the course of measuring Cs, it is unavoidable that Cs (stable) will be an impurity within the sample. In order to derive high-quality Cs data, it is necessary to also measure Cs. We have measured the neutron-capture cross-section of Cs using ANNRI at the MLF at J-PARC, in the energy region from thermal to 1.5 keV, via the time-of-flight method. This measurement has better statistics and covers a wider energy range than previous measurements of Cs. Additionally, we have confirmed the misassignment of various resonances from previous experiments.
