| 1 | Resonant Scattering of 22Na+p by Thick-Target Inverse Kinematic Method显示文摘22 Na is one of the most important yet debatable cosmic γ-ray emitters. The relative short half-life of 22 Na (T1/2=2.6 a) and the delayed 1.275 MeV γ-ray indicate that the 22Na may be a very sensitive probe to the nova outburst, especially for the nearby ONe novae from the Sun. | WANG You-bao JIN Sun-jun SU Jun YAN Sheng-quan LI Yun-ju GUO Bing LI Zhi-hong BAI Xi-xiang LIU Wei-ping H.Yamaguchi S.Kubono D.Kahl J.Hu H.S.Jung J.Y.Moon T.Teranishi H.W.Wang H.Ishiyama H.Iwasa H.Komatsubara | 2012 | Annual Report of China Institute of Atomic Energy2012，，1： | 0 |
| 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 | Study of Proton Resonances in ^(22)Mg by Resonant Elastic Scattering of ^(21)Na+p and Its Astrophysical Implication in ^(18)Ne(α,p) ^(21)Na Reaction Rate显示文摘Proton resonant states in 22Mg have been investigated by the resonant elastic scattering of 21Na+p. The 21Na beam with a mean energy of 4.00 MeV/u was separated by the CNS radioactive ion beam separator(CRIB) and bombarded a thick(CH2)n target. The energy spectra of recoiled protons were measured at scattering angles of θcm ≈172° and 146°,respectively. A new state at 7.06 MeV has been observed clearly and another new one at 7.28 MeV is tentatively identified due to its low statistics. The proton resonant parameters were deduced from an R-matrix analysis of the differential cross section data. The astrophysical resonant reaction rate for the 18Ne(α,p)21Na reaction has been estimated,and it is about five times larger than that assumed before. | S.Kubono T.Teranishi M.Notani H.Baba S.Nishimura J.Y.Moon M.Nishimura S.Michimasa H.Iwasaki Y.Yanagisawa N.Hokoiwa M.Kibe J.H.Lee S.Kato Y.Gono C.S.Lee | 2009 | 原子核物理评论2009，26，S1： | 0 |

| 5 | 用逆运动学厚靶方法研究22Na+p共振散射显示文摘正22Na是最重要但又有争议的宇宙γ射线发射体之一,其相对较短的衰变寿命(T1/2=2.6a)及其缓发的1.275MeVγ射线,使其有可能成为太阳系附近ONe新星爆发的灵敏探针。在新星形成过程中随温度提高有两种模式,即20Ne(p,γ)21Na(β+)21Ne(p,γ)2Na或20Ne(p,γ)21Na(p,γ)22Mg(β+)22Na可生成22Na, | 王友宝 金孙均 苏俊 颜胜权 李云居 郭冰 李志宏 白希祥 柳卫平 H.Yamaguchi S.Kubono D.Kahl J.Hu H.S.Jung J.Y.Moon T.Teranishi H.W.Wang H.Ishiyama N.Iwasa H.Komatsubara | 2012 | 中国原子能科学研究院年报2012，，1： | 0 |
