Abstract	configurational representation: spherical neutron halo nuclei M. Stoitsov, P. Ring, D. Vretenar and G.A. Lalazissis 1Institute for Nuclear Research and Nuclear Energy, Bulgarian Academy of Sciences, Sofia–1784, Bulgaria 2 Physik-Department der Technischen Universität München, D-85748 Garching, Germany 3 Physics Department, Faculty of Science, University of Zagreb, Croatia ̃ The scaled harmonic oscillator basis (SHO) is derived by a local scalingpoint transformation of the spherical harmonic oscillator radial wave functions. The unitary scaling transformation produces a basis with improved asymptotic properties. The SHO basis is employed in the solution of the relativistic Hartree-Bogoliubov (RHB) equations in configurational space. The model is applied in the self-consistent mean-field approximation to the description of the neutron halo in Ne isotopes. It is shown that an expansion of nucleon spinors and mean-field potentials in the SHO basis reproduces the asymptotic properties of neutron densities calculated by finite element discretization in the coordinate space. In the RHB description of neutron skins and halos, SHO bases in two or three dimensions can be a useful alternative to technically complicated solutions on a mesh in coordinate space.
