| 1 | 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 |
| 2 | 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 |
