| 1 | 2-14 Investigation of the Thermonuclear 18Ne(α, p)21Na Reaction Rate via Resonant Elastic Scattering of 21Na + p显示文摘A nuclear astrophysics experiment was performed at CRIB (CNS low-energy Radioactive-Ion Beam separator)on Mar. 2011. The goal of this experiment is to study the reaction rate of 18Ne(,p)21Na reaction, which mightbe a key breakout reaction from the hot CNO cycle to rp-process in X-ray burst and nova. Yet its reaction rate ispoorly known.Explosive hydrogen burning is thought to be the main source of energy generation and a source of nucleosynthesisin X-ray burst and nova[1;2]. For example, XRBs are characterized by a sudden increase of X-ray emission withinonly a few seconds to a total energy output of about 1040 ergs, which is observed to repeat with some regularity.The recurrence time for single bursts can range from hours to days at the typical temperature of 0.4~2 GK. Thebursts have been interpreted as being generated by thermonuclear runaway on the surface of a neutron star thataccretes H- and He-rich material from a less evolved companion star in a close binary system. As shown in Fig. 1,under its typical temperature, the hydrogen burning in X-ray burst occurs from the hot CNO cycle: | Zhang Liyong He Jianjun Xu Shiwei H.Yamaguchi S.

| 2 | Neutron and Alpha Structure in Neutron Deficient Nuclei in Astrophysics显示文摘The paper includes discussions on the important role of neutron and alpha configurations in proton-rich nuclei in nuclear astrophysics in terms of nucleosynthesis under extremely high-temperature hydrogenburning conditions. The νp-process, which is supposed to take place at the very early epoch of type II supernovae, has considerable neutrons and alphas together with protons. The alpha-induced reactions on proton-rich unstable nuclei in the light mass regions is expected to play a crucial role, but very few of them were investigated well yet because of the experimental difficulties. Specifically, I report our recent experimental effort for the breakout process from the pp-chain region,~7Be(α, γ)^(11)C(α,p)^(14)N under the νp-process. The neutron-induced reactions on proton-rich nuclei, which is even more a challenging subject, were investigated previously for very few nuclei. One possible experimental method is the Trojan Horse Method(THM). We successfully have applied THM to the ^(18)F(n,α)^(14)N reaction study with an unstable beam of ^(18)F. | S.Kubono 何建军 H.Yamaguchi D.M.Kahl S.Hayakawa T.Teranishi S.Cheribini M.Gulino Y.K.Kwon T.Hashimoto Y.Wakabayashi N.Iwasa S.Kato T.Komatsubara D.N.Binh L.H.Khiem N.N.Duy T.Kawabata C.Spitaleri G.G.Rapisarda M.La Cognata L.Lamia R.G.Pizzone S.Romano A.Coc N.de Sereville F.Hammache G.Kiss S.Bishop | 2016 | 原子核物理评论2016，33，2： | 0 |
| 3 | ~1H(^(17)F,α)^(14)O反应截面测量显示文摘^(14)O(α, p)^(17)F是天体X射线暴中重要的突破反应。本工作通过厚靶方法测量其逆反应~1H(^(17)F,α)^(14)O的反应截面来研究这一关键反应。本实验工作是在日本东京大学原子核科学研究中心(CNS)的低能次级束流线(CRIB)上完成的,后续的扣除本底实验是在兰州放射性束流线(RIBLL1)上完成的。CRIB实验是通过~2H(^(16)O,n)^(17)F转移反应产生^(17)F次级束,经过CRIB分离提纯之后,利用该次级束轰击氢气靶。在氢气靶后布置了三套望远镜探测器系统,用以探测不同实验角度的反冲α粒子,在数据处理的过程中经过动力学重构后得到了~1H(^(17)F,α)^(14)O反应在质心系能区E_(c.m.)=2.7~3.4 MeV的反应截面。实验结果在3 MeV以上的高能区与前人的薄靶实验数据是一致的,在低能区本工作获得了新的实验数据,倾向于支持干涉相消的理论预言结果。 | 贾宝路 胡钧 何建军 许世伟 H.Yamaguchi D.Kahl 马朋 苏俊 王宏伟 T.Nakao Y.Wakabayashi T.Teranishi K.I.Hahn J.Y.Moon H.S.Jung T.Hashimoto A.A.Chen D.Irvine C.S.Lee S.Kubono | 2019 | 原子核物理评论2019，36，1： | 0 |
