项目摘要

Recently, the nuclear data related to charged particles are becoming important for ion beam applications, cancer therapy, estimation of the affects of space radiations, synchrotron radiation source, neutron science, treatment of spent nuclear fuels, new atomic energy system, and so on.To enforce these applications effectively and in safe, it needs to preparer the basic nuclear data bases and for these new applications, there needed are various nuclear data, in addition to the usual nuclear data related to the fission reactor plants now used. Necessary data distribute widely in incident energy and in target nucleus. Since data on nucleon-incident and emission are evaluated now extensively, we attempted to evaluate those of one-nucleon transfer reactions, like (n, d), (p, d), and their inverse reactions. The experiments are done using Tandem accelerators of Kyushu- and Tsukuba- Universities, and continuum spectra are measured with polarized beam and analyzed with direct reaction model. Analysis of continuum spin spectra with direct reaction model is new and the method to analyze the 10-20MeV excitation energy spectra has been established. In addition, several technical developments are performed. All these results are reported widely in meetings, conferences and journals.

近年来，与带电粒子有关的核数据在离子束应用、癌症治疗、空间辐射影响评估、同步辐射源、中子科学、乏燃料处理、新型原子能系统等方面变得越来越重要。为了有效和安全地实施这些应用，需要准备基本的核数据库，为了这些新的应用，除了与现在使用的裂变反应堆工厂有关的通常的核数据外，还需要各种核数据。必要的数据在入射能量和靶核中分布广泛。由于现在对核子入射和发射的数据进行了广泛的评估，我们试图评估单核子转移反应的数据，如（n, d），（p, d）及其反反应。在九州大学和筑波大学的串联加速器上进行了实验，用偏振光束测量了连续光谱，用直接反应模型分析了连续光谱。用直接反应模型分析连续自旋能谱是一种新方法，建立了分析10-20MeV激发能谱的方法。此外，还进行了一些技术开发。所有这些结果都在会议、会议和期刊上广泛报道。
