Nuclear Physics by High Energy Heavy-Ion Beams

本研究计划旨在以全国综合的观点，重新研究目前各能区正在进行的重离子物理研究计划，以推动高能重离子束在核物理中一个有特色的新领域。本研究项目为期3年，1996- 1998年。当这个项目启动时，核物理学界要求已久的日本强子计划（JHP）正处于转折点。新提案提议通过合并现有的两个研究所KEK和INS来创建新的组织。根据这种情况，加速器计划从30 GeV改为50 GeV。因此，我们不得不相应地调整我们的物理计划。核物理学界的“核物理委员会”（Kaku Butsuri Iinkai）进行了一系列的研究。在这三年中，每年定期举行约4次会议。最后，这个名为“高能加速器研究组织”（KEK）的新组织幸运地于1997年成立，这是该研究计划的最后一年。我们对这个研究项目所发挥的作用感到非常自豪。除此之外，这个研究项目还支持了许多专题讨论会和讲习班。当然，在这个项目的支持下，也有一些新的核物理学科。请向个别调查员索取个别物品。在这份报告中，我们只将第一次和最后一次会议报告作为纪念报告。

This research program is aimed at to promote a characteristic new field in nuclear physics by the high energy heavy-ion beams by re-studying the presently on-going heavy-ion physics programs in various energy regions based on the comprehensive standpoint of nationwide. The period of this research program was 3 years of 1996-8.When this program started, the the Japan Hadron Project (JHP) which had been demanded by the nuclear physics community for long time, was just making a turn. The new proposal was proposed to create new organization by unifying two existing institutes, KEK and INS.According to this scenario the accelerator plan was changed to 50 GeV from 30 GeV.Due to this, we had to adjust our physics plan accordingly. A series of study was made by the the "Nuclear Physics Committee" (Kaku Butsuri Iinkai) of nuclear physics community. The meetings were held regularly about 4 times per year for these 3 years. And at last the new organization named "High Energy Accelerator Research Organization" (KEK) has fortunately been established in 1997, last year of this research program. We are very proud of the role which was playd by this research program.Beyond that, this research program has supported many symposia and workshops. Of course there are also a number of newly created subjects in nuclear physics under the support of this program. Please ask the individual investigators for the individual items. In this report we included only the first and the last meeting reports as memorial ones.
