摘要
对9≤A≤14,3≤Z≤5的核进行了壳模型计算.以8He作为core,选用修正的表面δ相互作用(MSDI)作为残余相互作用,挑选了24个实验能谱数据,定出了MSDI的参数和单粒子能量,并计算了结合能、低激发谱、电磁性质等,得到与实验较符合的结果.并着重讨论了"Be的宇称反转和halo结构的物理机理.计算程序为OXBASH.
A shell model calculation is carried out for nuclei with 9≤A≤14 and 3≤Z≤5. In the calculation 8He is treated as a core. The data for 24 experimental energy spectra are selected to determine the parameters of the modified surface δinteraction (MSDI) and the single-particle energies. The RMS=0.72MeV. Then the binding energies, the low-lying excited energy spectra and the electromagnetic properties are calculated and the results are in good agreement with experiment in general. The micromechanism of the halo structure and the parity conversion of the 11Be are discussed in detail. This work is carried out with the OXBASH code.
