英文摘要: We study the level structures of N = 7 similar to 9 isotones and their mirror nuclei in the framework of the single-particle potential model. Considering the limitation of the conventional potential-model calculation, the isospin-dependent l(2) coupling is newly introduced in the average potential. The modified model gives a unified description for the structures of all studied nuclei. Calculations self-consistently produce the s-d level inversion in N = 9 isotones and their mirror nuclei. Meanwhile, the s-p level inversion in the mirror nuclei (11)Be and (11)N is reproduced. The study confirms the neutron halo structures in (11)Be(2s(1/2)), (11)Be(1p(1/2)), (12)B(2s(1/2)), (14)B(2s(1/2)), (13)C(2s(1/2)), (15)C(2s(1/2)) and the proton halo structure in (17)F(2s(1/2)). The agreement between theory and experiment indicates that the inclusion of the l(2) coupling is a feasible way to explain the abnormal structures of exotic light nuclei.
