Description

We have studied nuclear reactions for Long-Lived-Fission-Products (LLFP) 90Sr for the purpose of nuclear transmutation. The nuclear data of proton and deuteron beam for LLFP target is one of the essential dataset for the study of transmutation. However, the nuclear data for those LLFP are insufficient and the accumulation of precise nuclear data is required. The interaction cross sections (σ_I) for 90Sr on C, CH_2, and CD_2 targets were measured in inverse kinematics using secondary beam of 90Sr of which beam energy was 190 MeV/nucleon at Radioactive Isotope Beam Factory (RIBF), RIKEN [1]. The cross sections of 90Sr on proton and deuteron have been obtained for the first time by this work. The transmission method was employed to measure σ_I. In order to determine σ_I for 90Sr on proton / deuteron, reaction on C target have been subtracted from reaction on CH_2 / CD_2 target. The preliminary experimental results will be shown with the comparison to the Glauber model [2]. The experimental setup, analysis method, and the result of comparison will be also introduced.
