Research Abstract	本研究課題は、平成4、5、6年度の3年間にわたるもので、平成6年度が最終年度にあたっていた。この課題に包括された的具体的研究テーマは次の通りであった。軽・重イオン核反応のダイナミクス、少数核子系の物理、核子系多体クラスター相関、前平衡・複合核の物理、核分裂・核融合のダイナミクス、低・中・高エネルギー核反応とハドロン生成過程、スピン偏極現象、天体核反応と元素生成、短寿命核の構造、不安定核生成と入射核反応、ハイパー核の生成・崩壊等。これらの諸現象にみられる量子動力学の諸様相を明らかにし、研究の展望を総括することを試みた。過去2年間の各個研究の成果をもとに、研究交流を行ない、研究成果の総括を行なうために、全国規模の研究討論の会議を開催した。研究会は「核反応が開く新しい原子核像-新自由度の導入、新分野への展開、着実な発展-」と題され。平成6年6月23、24、25日の3日間、大阪大学核物理研究センターにおいて開催された。講演者は、本研究課題の分担者に限らず、また、実験核物理研究者にも招待講演の形で参加を要請し、計47名にのぼった。研究成果の発表・討議は活発で、有意義な研究会であった。報告された内容は、1人5ページ(英文)を標準に文書にまとめ、印刷されて、この報告書に添付される「研究成果の報告書」冊子の一部に掲載報告されるとともに、一般に配布公開される。
