Apr 2000 中性子ハローをもつ原子核の研究

中性子過剰核には、中性子が弱く束縛される中性子ハローをもつ原子核が存在する。核半径を求めるため全反応断面積測定を行い、ハロー中性子の軌道を調べるため、neutron removal反応の測定を行う。

Apr 1994 短寿命核の構造研究

これまでの研究により、自然界で安定に存在する原子核(安定核)は理解されている。しかし、自然界で短い寿命しか持てない原子核(短寿命核)の中には、安定核とは異なる構造を持つものがある。このような原子核を見つけ、短寿命核の非弾性散乱(クーロン励起)や核子移行反応で励起し、励起状態のエネルギー、核スピン、遷移確率等を測定することで、異なる構造を持っている理由を調べる。

Apr 1991 天体核反応の研究

星の進化や元素に存在比を理解するため、星などで起きている原子核反応の断面積を測定する。
