| 1 | Observation of New Isotope^(131)Ag via the Two-Step Fragmentation Technique显示文摘We report on the first observation of the neutron-rich nucleus^(131)Ag.This isotope was produced via fragmentation reactions of intense secondary radioactive ion beams,including 134,135Sn.The secondary beams were produced from induced fission reactions from a stable 238U beam at 345 MeV/nucleon.Secondary reaction residues were selected by the ZeroDegree spectrometer and identified by measuring their magnetic rigidity,time of flight,energy loss,and total kinetic energy. | 王赫 N.Aoi S.Takeuchi M.Matsushita P.Doornenbal T.Motobayashi D.Steppenbeck K.Yoneda K.Kobayashi J.Lee 刘红娜 Y.Kondo R.Yokoyama H.Sakurai 叶沿林 | 2013 | Chinese Physics Letters2013，30，4： | 0 |
| 2 | 丰中子核^(63,65,67)Mn的在束γ谱学研究显示文摘利用放射性束68Fe轰击液氢靶引起的敲出反应,研究了极端丰中子核^(63,65,67)Mn的激发态,指认了它们的自旋宇称,建立了这三个原子核的能级纲图。纲图包含11/2^(-)、9/2^(-)和7/2^(-)三个激发态以及5/2^(-)_(g.s.)基态,它们由三条ΔI=1的γ跃迁连接。这种能级结构与K=5/2时强耦合转动带的特征一致。使用改进的LNPS有效相互作用(LNPSm)的大规模壳模型计算能很好地重现观测到的能级。计算表明,^(65,67)Mn的低位激发态都主要包含处于4p-4h的中子组态和1p-1h的质子组态。基于实验结果发现,在吸积中子星壳中,与质量数A=63相关的Urea中微子冷却效果比预期的要强很多,而A=65,67的冷却效果比预期的更弱。 | 卢洪洋 刘小雨 丁兵 刘忠 P.Doornenbal A.Obertelli S.MLenzi P.M.Walker L.X.Chung B.D.Linh G.Authelet H.Baba D.Calvet F.Chateau A.Corsi A.Delbart J.M.Gheller A.Gillibert T.Isobe V.Lapoux M.Matsushita S.Momiyama T.Motobayashi M.Niikura F.Nowacki H.Otsu C.Peron A.Peyaud E.C.Pollacco J.Y.Rousse H.Sakurai M.Sasano Y.Shiga S.Takeuchi R.Taniuchi T.Uesaka H.Wang K.Yoneda | 2020 | 原子核物理评论2020，37，3： | 0 |
| 3 | New Measurements for ^(8)He Excited States显示文摘Breakup reactions of the double borromean nucleus ^(8)He were measured at 82.3 MeV/u on CH2 and C targets.The coincident detection of two decaying neutrons and the high performance for neutron cross talk rejection are realized in this experiment.The relative energy spectrum for ^(8)He was reconstructed with good statistics.The spectrum exhibits a structure of two resonant peaks,one at an excitation energy of about 3.0 and the other at about 4.14 MeV,respectively.Substantially larger cross section for the first resonance is observed in comparison to the results reported previously. | 肖军 叶沿林 曹中鑫 江栋兴 郑涛 华辉 李智焕 李湘庆 葛愉成 楼建玲 庞丹阳 吕林辉 李奇特 乔锐 游海波 陈瑞九 H.Sakurai H.Otsu M.Nishimura S.Sakaguchi H.Baba Y.Togano K.Yoneda 李琛 王硕 王赫 李阔昂 Y.Nakayama Y.Kondo S.Deguchi Y.Satou K.H.Tshoo | 2012 | Chinese Physics Letters2012，29，8： | 0 |
