Abstract：
The structures of N=7 and N=8 isotones in Be-F mass range are investigated in the framework of the single-particle shell model. Different from the traditional potential terms, the l² coupling is included in the average nuclear potential. Calculations give a unified description for the structures of all studied nuclei. The neutron s-p level inversion in ¹¹Be and proton s-d level inversion in ¹⁶F are simultaneously reproduced. In addition, the neutron halo structures in ¹¹Be(2s_1/2) and ¹¹Be(1p_1/2) are obtained. The proton halo in the first-excited state of ¹⁷F is also discussed.
