| 1 | Calculations of electric quadrupole moments and charge radii for high-K isomers显示文摘Configuration-constrained potential-energy-surface calculations are performed to investigate high-K isomers in97Y,130Ba,176Yb,177Lu,and178Hf that were observed to have increased electric quadrupole moments but decreased charge radii relative to the states on which they are built.Taking into account the efects of deformation change and unpaired protons,our calculations can reproduce the enhancement of electric quadrupole moments for the isomers in97Y,130Ba,176Yb,177Lu and the Kπ=8 isomer in178Hf,and can reproduce the reduction of charge radii for the Kπ=27/2 isomer in97Y and the Kπ=16+isomer in178Hf. | LIU HongLiang XU FuRong | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 5 |
| 2 | Collective properties of neon isotopes investigated by projected shell model显示文摘Collective phenomenon in neon isotopes is an interesting topic.However,even the ground-state deformations cannot be well described by theories.Recently,QJ Zhi and ZZ Ren[Phys Lett B 638:166(2006)]have suggested an improved Nilsson potential,which can give a suitable description of ground-state properties in magnesium isotopes.In order to test the description of neon isotopes located around the‘‘island of inversion’’,we have used this potential to provide the deformed basis for the projectedshell-model calculations.The low-lying spectra and transition properties of neon isotopes can be reproduced reasonably.The gyromagnetic factors of neon isotopes have also been investigated.The structures of excited states along the yrast line are studied in the language of band diagrams. | Guoxiang Dong Xiaobao Wang Furong Xu Shaoying Yu | 2014 | Chinese Science Bulletin2014，59，29： | 2 |
| 3 | Nuclear dynamical octupole deformation in heavy-ion reactions显示文摘在量以内分子的动力学(QMD ) 模型,动态 octupole 变丑在重离子的熔化反应的来临的过程作为在射弹和目标之间的中央距离的功能被学习。事件精力上的最大的动态 octupole 变丑的依赖也被调查。动态 octupole 变丑能在来临的过程期间被观察,并且最大的动态 octupole 变丑与减少的事件精力变得更重要。在射弹和目标的质子和中子中心的分布也分别地被调查。在重离子的熔化反应的来临的过程,因为强壮的库仑潜力,在二个原子核的质子中心之间的分离在中子中心之间比那大。 | Cheng Tang Xin Jin Nan Wang En-Guang Zhao | 2015 | Frontiers of physics2015，10，5： | 0 |
| 4 | On the structure of isomeric state in neutron-rich 108Zr: A projected shell model analysis显示文摘Inspired by the recent experimental identification of the new isomer with a half-life of(620±150) ns in the very neutron-rich nucleus 108 Zr, we apply the projected shell model with axially-deformed bases to discuss possible shapes near the ground state and the nature of the isomer. The structure of the new isomer is investigated by restricting the calculation to prolate and oblate shapes. It is shown that the isomer can be understood as a K-isomer. Meanwhile, the calculation predicts more low-lying high-K configurations, which may be confirmed by future experiments. | LIU YanXin YU ShaoYing SUN Yang | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，11： | 0 |
| 5 | Triaxiality and shape coexistence in the A ~ 30 “island of inversion”nuclei显示文摘Understanding the properties of nuclei inside 'island of inversion' is still an interesting issue. Based on a simple Nilsson model with a new set of isospin-dependent parameters, and with non-axial deformations considered, we have performed three-dimensional potential-energy-surface calculations for Ne, Na, Mg and Al isotopes that are claimed to be in or nearby the A~30 island of inversion'. It is found that shape coexistence and triaxial deformation(or softness) exist in these nuclei. Large deformations are obtained by the improved Nilsson parameters, which explains the observed large electric quadrupole transition probabilities. The large deformations happening in30 Ne,31Na,32 Mg and33Al indicate the quenching of the spherical N = 20 neutron shell gap. The calculations of nuclear binding and two-neutron separation energies have been also improved with the isospin-dependent parameters and the inclusion of the non-axial deformation degree of freedom. | DONG GuoXiang WANG XiaoBao YU ShaoYing | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，11： | 0 |
