摘要
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 structure of nucleus ^(11)Be is investigated in terms of Particle-Vibrator Model (PVM).The low-lying states and electro-dipole transition of the first excited state to ground state of ^(11)Be are calculated,and the results are in good agreement with experiments. The calculated wave-function of the ground state of ^(11)Be shows that the parity inversion was caused by coupling of single particle motion with collective vibration of cove (^(10)Be). The halo structure of ^(11)Be is also explained reasonably in terms of the PVM.
