Abstract：
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.
