Nuclear Physics and Nuclear Data
Outline Activities
I am working in the research field related to high-energy nuclear data which are needed for various accelerator-related applications, such as accelerator-driven transmutation systems, advanced cancer therapy with particle beams, space development, etc.: measurements of cross section data and their theoretcial analysis based on advanced nuclear reaction models. Also, I am doing research and development of a new type of accelerator-driven neutron source in the MeV region using Kyushu university tandem acclerator and studying cosmic-ray neutron induced soft error phenomena in semiconductor devices. My resposibility for eduaction is to teach and supervise students not only in the graduate course of the department of advanced energy engineering science but also in the undergraduate cources of the department of energy science and technology. As my social activities, I join some working groups in the Japanese Nuclear Data Committee, and teach the knowledge and topics on radiation to junior high and senior high school students in cooperation with the Japan Atomic Energy Relations Organization.

Theor. Exp. Phys., 10.1093/ptep/ptx110, 093D03 (10 pages), 2017.09, 理研RIBFにおいて逆運動学手法を用いて、長寿命核分裂生成物核種であるZr-93に対する105 MeV/核子 陽子・重陽子入射核破砕反応による同位体生成断面積を測定した。Zr、Y同位体生成量分布において、中性子魔法数N=50に起因すると思われるギャップを観測した。粒子・重イオン輸送計算コードPHITSに組み込まれている核反応理論モデル計算との比較の結果、計算は少数の核子を除去する反応の断面積を大きく過剰評価しており、現モデルの改良の必要性を明らかにした。本実験データは、核破砕反応が高レベル放射性廃棄物中のZr-93を処理する核反応プロセスの有力な候補であることを示唆している。.

Cu, and Nb at 102 MeV were measured at forward angles ≤25° by means of a time of flight (TOF) method with
NE213 liquid organic scintillators at the Research Center of Nuclear Physics (RCNP), Osaka University. The experimental DDXs and energy-integrated cross sections were compared with TENDL-2015 data and Particle and Heavy Ion Transport code System (PHITS) calculation using a combination of the KUROTAMA model, the Liege Intra-Nuclear Cascade model, and the generalized evaporation model. The PHITS calculation showed better agreement with the experimental results than TENDL-2015 for all target nuclei, although the shape of the broad peak around 50 MeV was not satisfactorily reproduced by the PHITS calculation..

The experimental result showed that the negative muon SEUs occur at about 3 times higher rate than the positive muon ones at the supply voltage of 0.5 V when the incident muons stop near the sensitive volume, because the capture of negative muon by atomic nuclei generates secondary ions with high LET in addition to direct ionization of incident muon..
