The ion storage ring, S-LSR has an electron beam cooler and a laser cooling system. The electron cooler for S-LSR was designed to maximize the effective cooling length in the limited drift space of the ring. Various experiments have been carried out using the electron beam cooling, such as the sweep electron cooling, the one-dimensional ordering experiment of protons, and the short bunch generation. The laser cooling experiment is also currently in progress. Concerning the one-dimensional ordering experiment, the first proton ordering was successfully confirmed. An abrupt drop in the momentum spread and the Schottky noise power have been observed at the proton number of 2000 with electron currents of 25 mA. The transition temperature of the proton ordering is 0.17 meV in the longitudinal direction.

リチウム同位体に関する14MeV中性子誘起核反応断面積の測定結果についてまとめた。測定には2個のガス比例計数管とシリコン検出器から成るカウンターテレスコープを用いた。Li(n,d)nHeとLi(n,t)nHeからの重陽子、三重陽子のスペクトルは終状態相互作用理論により解析された。これらの反応及びLi(n,t)He、Li(n,d)He反応の角度分布は有限レンジDWBAで解析され、分光学的因子が求められた。
