  Weakly-bound deformed nuclei have been studied by the Skyrme
Hartree-Fock-Bogoliubov (HFB) approach in large coordinate-space boxes. In
particular, the box-size dependence of the HFB calculations of weakly-bound
deformed nuclei are investigated, including the particle density and pairing
density distributions at nuclear surfaces, the near-threshold resonant and
continuum quasiparticle spectra, and energetic properties. The box size may
have larger influences in pairing properties than in other bulk properties. We
demonstrate that large-box calculations of weakly-bound nuclei are important to
precisely describe exotic phenomena such as deformed halos and peninsulas of
stability beyond drip lines.
