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(2s1/2) and 11Be(1p1/2) are obtained. The proton halo in the first-excited state of 17F is also discussed.
