Halo or Skin in the Excited States of Two Couples of Mirror Nuclei 13N-13C and 15N-15O

    Graphical Abstract
    • Abstract
  • Properties of two pairs of mirror nuclei 13N13C and 15N15O are investigated by using the nonlinear relativistic meanfield theory. It is found that all the calculated binding energies with two different parameter sets are very close to the experimental ones for both the ground states and the excited states. The calculations show that the first excited state (2s1/2) and the third excited state (1d5/2) in 13N are both unbound resonances with proton halo structure, whereas the third excited state (1d5/2) in 13C is weakly bound with a neutron skin. It is also predicted that there has a proton halo in the second excited state (2s1/2) of 15N as well as a neutron skin in the first excited state (2s1/2) of 15O.
