Description

We introduce a local-scaling point transformation to allow for modifying the asymptotic properties of the deformed three-dimensional Cartesian harmonic oscillator wave functions. The resulting single-particle bases are very well suited for solving the Hartree-Fock-Bogolyubov equations for spherical and deformed drip-line nuclei. We then present results of self-consistent calculations performed for the Mg isotopes and for light nuclei located at the two-neutron drip line. The results suggest that all two-neutron-drip-line isotopes of even-Z elements with Z = 10 to 18 have oblate ground-state shapes. (authors)
