This year is the last year of this research project on the nuclear excited states and their excitation mechanisms, in which we have settled the five main subjects to be studied. The theoretical studies on the superdeformed high spin states is steadily developed in accord with the development of the experimental studies. We had occasion to discuss the studies in the international conference on "Rapidly Rotating Nuclei" (0ct. 26-30, Tokyo). The studies on the molecule-like structures are also developed in connection with the high spin and with the more heavier nuclear clusters. The studies on the structure (halo-structure and soft modes) and reactions of unstable nuclei have shown a full scaled development under this research project. The regions of the studies have been expanded to the structures of heavier unstable nuclei and to the reactions in wide energies from subbarrier fusion to breakup fragmentation. The studies on the hypernuclei have been developed from S=-1(LAMBDA - and SIGMA -)hypernuclei to S=-2 (XI - and LAMBDA LAMBDA -)hypernuclei. The studies on the giant resonances (hard modes) are also progressed in connection with the quasi-elastic scatterings of high energy particles. The special meeting was held on 0ct. 5-6,1992 at Niigata Murakami city to make the summary of this research project. The summary is not only on the studies of the five fields but also all the studies in view of the mutual connections between these five reseach fields. Those summaries are collected in the book of the report.

今年是核激发态及其激发机制研究项目的最后一年，我们确定了五个主要研究课题。超变形高自旋态的理论研究随着实验研究的发展而稳步发展。我们有机会在“快速旋转核”国际会议（0ct.26-30，东京）上讨论了这些研究。对类分子结构的研究也与高自旋和更重的核团簇有关。不稳定核的结构（晕结构和软模式）和反应的研究在该研究项目下得到了全面发展。研究领域已扩展到较重的不稳定核的结构以及从亚势垒聚变到破裂碎片的宽能量反应。超核的研究已从S=-1(LAMBDA-和SIGMA-)超核发展到S=-2(XI-和LAMBDA LAMBDA-)超核。巨共振（硬模）的研究也与高能粒子的准弹性散射相关。特别会议于 0 点召开。 1992年5-6日在新泻村上市对本研究项目进行总结。总结不仅是对这五个研究领域的研究，而且是针对这五个研究领域之间相互联系的所有研究。这些摘要收集在报告书中。
