3D solution of HartreeFockBogoliubov equations for dripline nuclei
Abstract
We investigate the possibility of describing triaxial quadrupole deformations for nuclei close to the twoneutron drip line by the HartreeFockBogoliubov method taking into account resonances in the continuum. We use a Skyrme interaction to describe the HartreeFock hamiltonian and a densitydependent zerorange interaction to evaluate the pairing field. The meanfield equations are solved in a threedimensional cubic mesh. We study the stability of the twoneutron separation energies and of the description of the nuclear surface as a function of the number of active meanfield orbitals and of the size of the mesh. The even Ni isotopes are used as a test case and the accuracy as a function of quadrupole deformation is studied by performing constrained calculations. A first application to the study of the twoneutron separation energies in Ni isotopes up to the drip line is presented.
