在粒子-振动模型(PVM)的基础上研究了~(11)Be 核的基态特性、低激发态和电偶极跃迁,理论结果与实验符合很好.计算结果表明,~(11)Be 的基态是单核子运动与核芯~(10)Be 的表面集体振动相耦合的结果.~(11)Be 的晕结构也得到合理的解释.
The ground state properties, low excitation states and electric dipole transitions of ~ (11) Be nucleus are studied on the basis of Particle-Vibration Model (PVM). The theoretical results agree well with the experimental results. The calculated results show that ~ (11) Be The ground state is the result of the coupling of mononuclear motion with the surface collective vibration of the core ~ (10) Be. The halo structure of ~ (11) Be is also reasonably explained.
