| 1 | Collective Band Structures in the Neutron-Rich ^(107,109)Ru Nuclei显示文摘The levels in neutron-rich odd-A ^(107,109)Ru nuclei have been investigated by using γ -γ -and γ -γ -γ-coincidence studies of the prompt γ-rays from the spontaneous fission of 252Cf. The ground state bands and the negative parity bands are identified and expanded in both nuclei. Triaxial rotor plus particle model calculations indicate the ground state bands originate from v(d_(5/2)+g_(7/2)) quasiparticle configurations and the negative parity bands are from vh_(11/2) orbital. | 朱胜江 甘翠云 J.H.Hamilton A.V.Ramayya B.R.S.Babu 萨哈伊 W.C.Ma 龙桂鲁 邓景康 朱凌燕 李明 杨利明 J.Komicki J.D.Cole R.Aryaeinejad Y.K.Dardenne M.W.Drigert J.O.Rasmussen M.A.Stoyer S.Y.Chu K.E.Gregorich M.F.Mohar S.G.Prussin I.Y.Lee N.R.Johnson F.K.McGowan | 1998 | Chinese Physics Letters1998，15，11： | 1 |
| 2 | Reflection Asymmetric Shapes in the Neutron-Rich ^(140,143)Ba Isotopes显示文摘Level schemes for the neutron-rich ^(140,143)Ba nuclei have been determined by study of promptγ-rays in spontaneous fission of ^(252)Cf.The level pattern and enhanced E1 transitions betweenπ=+andπ=-bands show reflection asymmetric shapes with simplex quantum number s=+1 in ^(140)Ba and s=±i in ^(143)Ba,respectively.The octupole deformation stability with spin variation has been discussed. | 朱胜江 王牧歌 J.H.Hamilton A.V.Ramayya B.R.S.Babu W.C.Ma 龙桂鲁 邓景康 朱凌燕 李明 T.N.Ginter J.Komicki J.D.Cole R.Aryaeinejadv Y.K.Dardenne M.W.Drigert J.O.Rasmussen Yu.Ts.Oganessian M.A.Stoyer S.Y.Chu K.E.Gregorich M.F.Mohar S.G.Prussin I.Y.Lee N.R.Johnson F.K.McGowan | 1997 | Chinese Physics Letters1997，14，8： | 0 |
| 3 | ^(68)Ge、^(65)Ga及^(67)Ga的高自旋态研究显示文摘用在束γ谱实验技术,对^(68)Ge、^(65)Ga与^(67)Ga的高自族态进行了研究。所用核反应为^(46)Ti(^(25)Mg,xpxn),束流能量为68MeV。在^(68)Ge中,观测到新的8^+以上的多带结构、带间的交叉跃迁及一个新的可能具有大形变的带。新的微观模型(EXCITED FED VAMPIR)的计算结果与实验数据比较得到满意的符合。在^(65)Ga与^(67)Ga中,给出了这两种核的新的能级图,观测到集体性很强的带结构。 | 朱胜江 J.H.Hamilton A.V.Ramayya L.Chaturvedi J.Kormicki X.W.Zhao I.Y.Lee N.R.Johnson C.Backtach F.K.McGowan M.L.Halbert J.D.Cole | 1992 | 高能物理与核物理1992，16，6： | 0 |
