Abstract: The ground-state properties of N=3 isotones and mirror nuclei have been investigated in the Rrelativistic Continuum Hartree-Bogoliubov theory with the NLSH effective interaction. Pairing correlations are taken into account by a density-dependent δ-force. The calculations show that the proton density distributions of 8B and 9C have a long tail, the core has an increasing tendency of 9C and the paired off valence protons make the halo distribution shrink. The cross sections for the 8B(9C)+12C reaction which are consistent with the experimental data are calculated using the Glauber model. On the whole, we think that 8B is a one-proton halo nucleus and 9C is a two-proton halo nucleus.
