Structures of ¹⁷F and ¹⁷O, ¹⁷Ne and ¹⁷N in the Ground State and the First Excited State

The structures of two couples of mirror nuclei ¹⁷F and ¹⁷O, ¹⁷Ne and ¹⁷N in the ground state and in the first excited state are investigated using the relativistic mean-field approach. Two-proton halo in ¹⁷Ne in the first excited state and in the ground state and two-neutron halo in ¹⁷N in the first excited state are suggested. Meanwhile, one-proton halo in ¹⁷F in the first excited state and one-neutron halo in ¹⁷O in the first excited state are also suggested. The skin structure appears in ¹⁷F and ¹⁷N in the ground state.
