Local Density Approximation for Pairing Correlations in Nuclei
Abstract
We introduce a natural and simple to implement renormalization scheme of the Hartree-Fock-Bogoliubov (HFB) equations for the case of zero range pairing interaction. This renormalization scheme proves to be equivalent to a simple energy cut-off with a position or density dependent running coupling constant. Subsequently, we present self-consistent HFB calculations with a full consideration of the continuum of long chains of spherical tin and lead nuclei (essentially from one drip line to another) using the SLy5 interaction. In the pairing channel we use a zero range interaction, treated by means of this new regularization scheme.
