Effects of Pairing Correlations on Formation of Proton Halo in 9C

Properties for the ground state of 9 C are studied in the relativistic continuum Hartree-Bogoliubov theory with the NLSH, NLLN and TM2 effective interactions. Pairing correlations are taken into account by a density-dependent δ-force with the pairing strength for protons determined by fitting either...

Summary:Properties for the ground state of 9 C are studied in the relativistic continuum Hartree-Bogoliubov theory with the NLSH, NLLN and TM2 effective interactions. Pairing correlations are taken into account by a density-dependent δ-force with the pairing strength for protons determined by fitting either to the experimental binding energy or to the odd-even mass difference from the five-point formula. The effects of pairing correlations on the formation of proton halo in the ground state of 9C are examined. The halo structure is shown to be formed by the partially occupied valence proton levels p3/2 and p1/2.
