原子核物理において、少数多対問題、特に3体問題は未だに未解決で興味深い問題であり、いろいろな理論を用いて研究がなされてきた。その中でも$$^6$$Li+n反応は基礎物理としてだけでなく、応用問題としても重要である。$$^6$$Liは$$alpha$$+d、あるいは$$alpha$$+p+nという2体、又は3体で記述されるため、その中性子反応は3体、又は4体問題となる。本研究では$$^6$$Li+n反応を"n+$$alpha$$+d"の3対問題として離散化連続結合チャンネル法で記述する手法を開発する。

The few-body, especially three-body, problem is still an open (and therefore interesting) subject in nuclear physics, and has been studied intensively by various theoretical frameworks. The n + $$^6$$Li reactions are important not only from the basic interest but also from the application point of view. The $$^6$$Li nucleus is well described by the cluster model such as $$alpha$$ + d and $$alpha$$ + p + n. Therefore, it is necessary for us to treat the n + $$^6$$Li system with $$alpha$$ + p + n and $$alpha$$ + p + n + n models. In this work, we study the $$^6$$Li+n inelastic reactions applying the $$alpha$$ + d cluster model to $$^6$$Li and using the continuum-discredited coupled-channels (CDCC) approach.
