Spin and parity of the excited states of a neutron-halo nucleus ィイD111ィエD1Be

放射性光束的发展，通过投影碎片过程开辟了一个新的核物理领域：不稳定核的结构。The nucleus D111Be shows a remarkably large interaction radius and this is the best known case of a one-neutron halo nuclei。But， there is a little experim？information， and the effort to acquire knowledge in the various parity of the final state by using theイイD110イイD1Be （d， p）イD111イD1Be reaction。As for the D110 y D1 Be target， the BeO on platinum foil被使用。令人兴奋的状态的能量足以证明不稳定的核生命中的核是由他（d， p）反应是从伽马射线和β射线的测量和11倍的形成得到证实的。氧化物的危害是通过使用反向质子散射来测试的，发现有很多C和O与大约两个订单进行比较。因此，我们发现它很难衡量（d， p）反应质子的分析能力，这是通过使用这一目标而产生的。“极化的德国光束”是从京都大学串联加速器中获得的。离子源是原子光束类型，并在时间上对其进行了改进，该源源在D110目标的开发上进行了并行处理。10 nA的极化质子束可以稳定地通过重新建模辩论器喷嘴的冷却系统、弱场射频转换的磁铁、ECR电离器的泵送系统和电荷交换部分等方式来形成。极化德国测量可能通过安装设备的控制旋转的维也纳过滤器。The Management of the thin target ofイイD110エD1Be with a very thin support is the future subject。

The developments of radioactive beam, produced through the projectile-fragmentation process are opening a new field of nuclear physics : the structure of unstable nuclei. The nucleus ィイD111ィエD1Be shows a remarkably large interaction radius and this is the best known case of a one-neutron halo nuclei. But, there is a little experimental information, and the effort to acquire knowledge in the various parity of the final state by using the ィイD110ィエD1Be (d, p) ィイD111ィエD1Be reaction. As for the ィイD110ィエD1Be target, the BeO on platinum foil was used. The energy of the excited state arid the life of the unstable nucleus which was produced by he (d, p) reaction were examined from the measurement of the gamma ray and the beta ray, and the formation of 11Be was confirmed. The impurities of the oxide that the surface of platinum foil were examined by using the backward proton scattering, and it was found out that there were many C and O in comparison with Be about two orders. Therefore, it found out that it was difficult to measure the analyzing power for the proton of the (d, p) reaction by using this target.The polarized deuteron beam was obtained from the Kyoto University Tandem Accelerator. The ion source was the atomic-beam type and the improvement of time this source was done on a parallel with the development of the ィイD110ィエD1Be target. The polarized proton beam of several 10 nA could be formed stably by remodeling the cooling system of the dissociator nozzle, the magnet of the weak-field RF transition, the pumping system of the ECR ionizer and the charge exchange part and so on.The polarized deuteron measurement becomes possible by the installation of the device which controls the spin such as a Wien filter. The development of the thin target of ィイD110ィエD1Be with a very thin support is the future subject.
