项目摘要
This research project was advanced for three years from 1995 to 1997. The project was on the study of two kinds of reaction processes induced by high energy light ions, for which the theoretical analyzes with antisymmetrized molecular dynamics (abbreviated to AMD) are utilized. One kind of reaction process we studied was such type of reaction process like quasi-free elastic scattering or DELTA-hole excitation in (p, p') , (p, n) , or (^3He, t) . The other kind of reaction process was the so-called target fragmentation by light ion projectiles, The former half of the present three-year research project was devoted mainly to the study of the first kind of reaction process with many fruitful results, while the latter half of three years including this year was devoted mainly to the study of the second kind of reaction process. The study of the first kind of reaction process succeeded in reproducing many experimental data and made a big contribution in clarifying the preequilibrium reactio … More n mechanism. Furthermore, analyzes of reaction cross sections of proton induced reactions gave us important information on the two-nucleon collision cross sections in nuclear medium. In the study of the second kind of reaction process, we investigated the target fragmentation by light ion projectiles, by analysing the fragmentation reaction of ^<12>C nucleus by proton injection. This analysis was made by comparing with the fragmentation reaction of ^<12>C nucleus by ^<14>N injection. Furthemore, in addition to the comparison with heavy-ion induced fragmentation, we also compared the proton induced fragmentation of ^<12>C nucleus with the ^4He induced fragmentation of ^<12>C nucleus. We found large difference between proton induced fragmentation and heavy-ion induced fragmentation and clarified the reason of this difference. This study of the fragmentation reaction gave the motivation to the study of the structure of the neutron-rich Boron isotopes by the use of fragmentation reaction. The results of the fragmentation study of the neutron-rich Boron isotopes strongly suggested the usefulness of the fragmentation reaction for checking the clustering structure of the neutron-rich Boron isotopes.

该研究项目从1995年到1997年进行了三年。该项目是在研究高能光离子引起的两种反应过程的研究,为此,利用了反对称分子动力学的理论分析(缩写为AMD)。我们研究的一种反应过程是这种类型的反应过程,例如(p,p'),(p,n)或(^3he,t)中的无准弹性散射或三角孔兴奋。另一种反应过程是轻离子弹丸所谓的靶标碎片化,目前三年研究项目的前半部分主要致力于对第一种反应过程的研究,并取得了许多富有成果的结果,而包括今年(包括今年)的后半部分主要致力于第二种反应过程的研究。对第一种反应过程的研究成功地繁殖了许多实验数据,并在确定预先验证反应的方面做出了巨大贡献……更多的N机制。此外,对质子诱导反应的反应横截面的分析为我们提供了有关核培养基中两核子碰撞截面的重要信息。在对第二种反应过程的研究中,我们通过分析质子注射的 ^<12> C核的碎片反应研究了光离子弹丸的靶片段化。通过与 ^<12> C核的碎裂反应相比,通过注射 ^<12> c核的碎裂反应进行了分析。此外,除了与重离子诱导的片段化的比较外,我们还比较了质子诱导的 ^<12> c核的片段和 ^4E诱导的 ^<12> C核的片段化。我们发现质子诱导的碎片和重离子诱导的碎片之间存在很大的差异,并阐明了这种差异的原因。这项对碎片反应的研究为研究了富含碎片反应的富含中子硼同位素的结构的动机。富含中子的硼同位素的片段化研究的结果强烈表明,碎片反应在检查富含中子硼同位素的聚类结构中的有用性。较少的
