Study of weakly-bound odd-A nuclei with quasiparticle blocking

Abstract

The coordinate-space Hartree-Fock-Bogoliubov (HFB) approach with quasiparticle blocking has been applied to study the odd-A weakly bound nuclei ${}^{17,19}$B and ${}^{37}$Mg, in which halo structures have been reported in experiments. The Skyrme nuclear forces SLy4 and UNEDF1 have been adopted in our calculations. The results with and without blocking have been compared to demonstrate the emergence of deformed halo structures due to blocking effects. In our calculations, ${}^{19}$B and ${}^{37}$Mg have remarkable features of deformed halos.
