Abstract：
The structures ofN=7 andN=8 isotones in Be-F mass range are investigated in the framework of the single-particle shell model. Different from the traditional potential terms, thel²coupling is included in the average nuclear potential. Calculations give a unified description for the structures of all studied nuclei. The neutrons-plevel inversion in¹¹Be and protons-dlevel inversion in¹⁶F are simultaneously reproduced. In addition, the neutron halo structures in¹¹Be(2s_1/2) and¹¹Be(1p_1/2) are obtained. The proton halo in the first-excited state of¹⁷F is also discussed.
