| 4 | 第一性原理研究三体力对^(28)F和^(29)Ne低激发谱的影响显示文摘从手征有效场论的N^(3)LO两体和N^(2)LO三体核力出发,采用第一性原理方法(开壳原子核多体微扰理论)计算了^(28)F和^(29)Ne的低激发能谱,并以此研究手征三体力对反转岛区域原子核性质的影响.通过对比采用纯两体与两体加三体力计算的^(28)F和^(29)Ne的低激发能谱,发现手征三体力对反转岛内原子核基态宇称反转现象有着重要的贡献.为了进一步探究三体力的影响,系统计算了丰中子Ne同位素的偶偶核基态波函数中的组态成分.结果显示,三体力显著地加强了跨壳激发效应,使理论计算与实验结果更加符合. | 戴博 李健国 张爽 王思敏 许甫荣 | 2021 | 科学通报2021，66，30： | 1 |
| 5 | 利用EQMD模型对原子核基态性质的研究显示文摘和中高能重离子碰撞相比,低能重离子碰撞中的弹靶结构效应起着更为重要的作用,因此要求输运模型能够对核的基态性质给出更合理的描述。利用扩展的量子分子动力学(EQMD)模型计算了从轻到重不同质量区不同同位素链的结合能及方均根半径等基态性质,并与实验值进行了比较,发现EQMD模型不仅能够非常好地重现稳定核的基态性质,而且能够合理地描述远离β稳定线核的基态结合能,因此相比于IQMD,CoMD,ImQMD等其他QMD版本,EQMD模型对初始化核稳定性的描述也有了极大改善。这为利用微观动力学模型研究弱束缚核在低能区引起的弹性散射、熔合、转移及破裂等反应机制提供了基础。 | 王闪闪 曹喜光 张同林 王宏伟 张国强 方德清 钟晨 马春旺 何万兵 马余刚 | 2015 | 原子核物理评论2015，32，1： | 1 |

| 7 | Extending the nuclear chart by continuum:From oxygen to titanium显示文摘Nuclear masses ranging from O to Ti isotopes are systematically investigated with relativistic continuum Hartree-Bogoliubov(RCHB)theory,which can provide a proper treatment of pairing correlations in the presence of the continuum.From O to Ti isotopes,there are 402 nuclei predicted to be bound by the density functional PC-PK1.For the 234 nuclei with mass measured,the root mean square(rms)deviation is 2.23 MeV.It is found that the proton drip-lines predicted with various mass models are roughly the same and basically agree with the observation.The neutron drip-lines predicted,however,are quite diferent.Due to the continuum couplings,the neutron drip-line nuclei predicted are extended further neutron-rich than other mass models.By comparison with finite-range droplet model(FRDM),the neutron drip-line nucleus predicted by RCHB theory has respectively2(O),10(Ne),10(Na),6(Mg),8(Al),6(Si),8(P),6(S),14(K),10(Ca),10(Sc),and 12(Ti)more neutrons. | QU XiaoYing CHEN Ying ZHANG ShuangQuan ZHAO PengWei SHIN Ik Jae LIM Yeunhwan KIM Youngman MENG Jie | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 1 |
| 8 | 相互作用势对原子核α团簇结构的影响显示文摘本文使用扩展的量子分子动力学模型(Extension of quantum molecular dynamics,EQMD),通过调整泡利势参数,使模型计算出的原子核平均结合能和均方根半径更符合实验值和经验公式。在EQMD模型中加入动量相关势,根据无限大核物质的状态方程推导得到不同的核相互作用势参数,研究不同核势深度对4≤A≤40的α共轭核(N=Z,偶偶核)内的α团簇结构形成的影响。结果表明:核势越深越容易在α共轭核中产生α团簇结构;同时,核势深度的变化也会影响~(12)C和~(16)O原子核内α团簇的构型。 | 狄宣平 方德清 何万兵 马余刚 | 2021 | 核技术2021，44，3： | 1 |
| 9 | Particle-number fluctuation of pairing correlations for Dy isotopes显示文摘Within the relativistic mean field(RMF) theory, the ground state properties of dysprosium isotopes are studied using the shell-model-like approach(SLAP), in which pairing correlations are treated with particlenumber conservation, and the Pauli blocking effects are taken into account exactly. For comparison, calculations of the Bardeen–Cooper–Schrieffer(BCS) model with the RMF are also performed. It is found that the RMF+SLAP calculation results, as well as the RMF+BCS ones, reproduce the experimental binding energies and one- and twoneutron separation energies quite well. However, the RMF+BCS calculations give larger pairing energies than those obtained by the RMF+SLAP calculations, in particular for nuclei near the proton and neutron drip lines. This deviation is discussed in terms of the BCS particle-number fluctuation, which leads to the sizable deviation of pairing energies between the RMF+BCS and RMF+SLAP models, where the fluctuation of the particle number is eliminated automatically. | 程明建 刘朗 张逸新 | 2015 | Chinese Physics C2015，39，10： | 0 |
| 10 | 基于剩余质子-中子相互作用来描述和预言A≥100的核质量显示文摘剩余质子-中子相互作用对原子核质量和核子对关联的研究具有重要意义.本文对选定核的左上角和右下角相邻原子核的质量以及最后一个质子与中子剩余相互作用(δV_(1p-1n))进行了研究.在已有的奇核δV_(1p-1n)和偶核δV_(1p-1n)两个经验公式的基础上进行改变得到一个新的经验公式,这个经验公式可以同时描述奇核和偶核两种剩余相互作用.分别运用AME2012和AME2016数据库的实验值结合新的经验公式计算得到质量数A≥100的原子核质量分别与AME2012和AME2016数据库中的实验值进行比较.对比结果表明,本文的计算值与AME2012和AME2016数据库中的实验值较吻合(A≥100时,与AME2012比较得到的均方根误差(RMSD)≈138.4 keV;与数据库AME2016比较得到的RMSD≈141 keV).此外,运用本文新的经验公式结合一些已知的核质量(AME2012)预言了一些未知的核质量,对比发现,本文的预言值与AME2012和AME2016的结果也吻合,其中一些预言值与AME2016中的实验值也较接近.由此说明本文计算中质核和重核质量的精确性可与AME2012外推法相媲美. | 焦宝宝 | 2018 | 中国科学:物理学、力学、天文学2018，48，5： | 0 |
| 11 | 2-15 Thermonuclear Reaction Rates in rp Process of 64Ge(p,γ)65As and 65As(p,γ)66Se for Type-I X-ray Bursts显示文摘We have derived new thermonuclear 64Ge(p, )65As and 65As(p, )66Se reaction rates based on recently evaluatedproton separation energies[1] and large-scale shell model (LSSM) calculation. The precisely measured or evaluatedproton separation energies of Sp(65As) and Sp(66Se), are (90±85) keV and (1720±310) keV, respectively. Weutilized one-zone post-processing type I X-ray burst model[2] to investigate the astrophysical impact of our newrates. We found that the new experimental Sp(65As), resonant energies and spectroscopic factors estimated fromLSSM significantly affects the productions of nuclide in the range of 64≤A≤110 about one to ten times comparedto currently available JINA data sets, REACLIB[3]. | Lam Yihua He Jianjun Parikh Anuj | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 12 | 天体Ⅰ型X射线暴中的核物理显示文摘X射线暴(X-ray burst)是指天体的X射线亮度突然增强10~50倍的天文现象.它是发生在由一颗中子星(或者黑洞)和一颗伴随的“捐赠者”伴星(通常为红巨星)所构成的密近双星系统里的剧烈核过程.作为宇宙中发生最频繁的热核爆炸事件,X射线暴已广泛为国际上众多基于卫星的X射线观测站所观测和研究,其中包括2017年中国发射的“慧眼”硬X射线调制望远镜.核物理学家需要提供精确的核物理输入量,例如原子核质量、衰变寿命、核反应率等,结合天体物理模型,进而深入理解X射线暴中天文观测到的光变曲线、双星系统相应的天体物理环境参数,以及爆炸灰烬中的核素丰度分布等重要科学问题.本文针对天体Ⅰ型X射线暴中关键核反应研究进行了系统的阐述,详细介绍了X射线暴中的一些主要核合成过程,以及所需的关键核物理输入量,总结了相关研究方向的具体目标,为研究者指出了未来可能的研究方向. | 张立勇 胡钧 何建军 | 2020 | 科学通报2020，65，7： | 0 |

| 14 | 基于CSRe实验环等时性原子核质量测量显示文摘We have performed isochronous mass measurements for the neutron-deficient fp-shell nuclei[1]produced via projectile fragmentation of an energetic 58Ni beam.Special techniques have been applied to the current measurements and data analyses in order to increase the resolving power of isochronous mass spectrometry in the heavy ion storage ring CSRe in Lanzhou,e.g.,inserting a metal slit in the dispersion section of the ring,and using a new technique to correct the effects of the unstable magnetic fields of the RIBLL2-CSRe system.On the basis of the newly measured masses,several nuclear structure studies in the fp shell have been performed.Main results and conclusions from this work are summarized as follows. | Zhang Yuhu CSRe mass measurement collaboration | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
| 15 | Exact treatment of pairing correlations in Yb isotopes with covariant density functional theory显示文摘The effects of pairing correlation in Yb isotopes are investigated by covariant density functional theory with pairing correlations and blocking effects treated exactly by a shell model like approach(SLAP). Experimental one- and two-neutron separation energies are reproduced quite well. The traditional BCS calculations always give larger pairing energies than those given by SLAP calculations, particularly for the nuclei near the proton and neutron drip lines. This may be caused because many of the single particle orbits above the Fermi surface are involved in the BCS calculations, but many of them are excluded in the SLAP calculations. | 刘朗 赵鹏巍 | 2014 | Chinese Physics C2014，38，7： | 0 |
