1^(183)Au核高自旋态转动带结构研究显示文摘通过重离子熔合蒸发反应和在束核谱学实验方法研究了奇A核183Au的高自旋态能级结构.扩展并更新了183Au的能级纲图.首次建立了183Au的πi13/2转动带的能量非优先带.分析并讨论了183Au中πh9/2转动带的能量非优先带和πf7/2转动带间的相互作用.宋立涛 周小红 张玉虎 郭应祥 雷相国 郑勇 柳敏良 G.de Angelis N.Marginean A.Gadea D.R.Napoli M.Axiotis C.Rusu T.Martinez 2005高能物理与核物理2005,29,8:0
2首次发现A=130核区中的t-band显示文摘Backbending played a pivotal role in the progress of high-spin structure research[1].This phennomenon was interpreted as a result of band-crossing between two intrinsic configurations which dominate lower-and higher-spin region.Usually the two configurations are differed by two nucleons,which are paired in the former,and unpaired in the latter.According to the strong-coupling scheme,two unpaired quasi-particles can couple to both high-K and low-K configurations in deformed nuclei.Usually only the lower can be identified experimentally since it is favoured by the Gallagher-Moszkowski spin-spin coupling rules[2].Guo Song Qiang Yunhua C.M.Petrache Liu Minliang Wang Jianguo A.Astier B.F.Lv D.Bazzacco G.de Angelis Fang Yongde Li Guangshun Zheng Kuankuan Li Ren A.Goasduff K.Hadynska G.Jaworski D.R.Napoli M.Siciliano J.J.Valiente-Dobon 2018IMP & HIRFL Annual Report2018,,1:0
3双奇核^(184)Au中πi_(913/2)νi_(13/2)转动带的结构特征研究显示文摘利用重离子熔合蒸发反应和在束γ谱学实验方法 ,研究了双奇核184 Au的高自旋态能级结构 .扩展了基于πh9/ 2 ν7/ 2 - [5 14 ]和πi13/ 2 νi13/ 2 2准粒子组态下的转动带能级纲图 ,建立了两个转动带之间以及πh9/ 2 ν7/ 2 - [5 14 ]带与基态的谱学连接 .从而确定了πi13/ 2 νi13/ 2 带能级的自旋和宇称 ,证实了此转动带在低自旋区出现旋称反转 .分析了πi13/ 2 νi13/ 2 带和相邻核转动带的准粒子顺排特征 ,指出此带的第一回弯以及相邻核转动带在低频观测到的顺排异常可能与h9/ 2 质子顺排有关 .张玉虎 王华磊 柳敏良 周小红 郭文 G.de Angelis N.Marginean A.Gadea D.R.Napoli M.Axiotis C.Rusu T.Martinez 许甫荣 2004高能物理与核物理2004,28,9:0
4^(94)Mo高自旋态能级纲图(英文)显示文摘通过重离子融合蒸发反应16 O(82 Se +4n) 94 Mo布局了94 Mo核的高自旋态 .利用多探头探测器阵列GASP进行了在束γ测量 ,从而重新研究了94 Mo核的高自旋态能级结构 .基于新发现的一些重要的连接跃迁 ,对94 Mo核的高自旋态能级纲图做了重要修改 .将新的能级结构与壳模型计算进行了比较和讨论 .结果表明要正确的描述94 Mo核的高自旋态 (自旋值大于 14 )能级结构 ,应考虑价中子在d5/ 2 ,g7/ 2 和h11/ 2 轨道上的激发 .张玉虎 柳敏良 G.de Angelis Zs.Podolyak 郭文涛 A.Gadea C.Ur N.Marginean C.Rusu R.Schwengner D.R.Napoli R.Menegazzo S.Lunardi D.Bazzacco T.Martinez M.Axiotis A.Gargano S.M.Lenzi F.Brandolini W.von Oertzen 2004高能物理与核物理2004,28,9:0
5Coexsitence of Three Foundamental Symmetries in One Nucleus显示文摘Near degeneracy between two quantum states is usually associated with fundamental symmetries and symmetry breakings in complex many-body systems like atomic nuclei.Pseudospin symmetry was introduced to describe energy degeneracy between single-particle states with quantum numbers(n,l,j=l+1/2)and(n-1,l+2,j=l+3/2)[1-3].Guo Song Qiang Yunhua C.M.Petrache Liu Minliang Wang Jianguo A.Astier B.F.Lv D.Bazzacco G.de Angelis Fang Yongde Li Guangshun Zheng Kuankuan Li Ren A.Goasduff K.Hadynska G.Jaworski D.R.Napoli M.Siciliano J.J.Valiente-Dobon 2019IMP & HIRFL Annual Report2019,,1:0
6^(130)Ba中同质异能态上的能级结构显示文摘Isomeric I^(π)=8^(-) states have been observed in the even-even N=74 nuclei ^(138)Gd[1],^(136)Sm[2],^(134)Nd[3],^(132)Ce[4],^(130)Ba[5],^(128)Xe[6]with half-lives ranging from nanoseconds(Xe)to milliseconds(Ba,Ce).Rotational bands built on the K^(π)=8^(-) isomer were identified in all these isotones,with the exception of 130Ba.The singleparticle configuration of the isomers have been deduced from theΔI=2 toΔI=1γ-ray intensity branching ratios,which allowed to extract the(gK��gR)/Q0 values,and therefore the quasi-particle configuration of the state.Guo Song Qiang Yunhua C.M.Petrache Liu Minliang Wang Jianguo A.Astier B.F.Lv D.Bazzacco G.de Angelis Fang Yongde Li Guangshun Zheng Kuankuan Li Ren A.Goasduff K.Hadynska G.Jaworski D.R.Napoli M.Siciliano J.J.Valiente-Dobon 2017IMP & HIRFL Annual Report2017,,1:0
