Contact Pairing Interaction for the Hartree-Fock-Bogoliubov Calculations

摘要

Properties of density-dependent contact pairing interactions in nuclei arediscussed. It is shown that the pairing interaction that is intermediate between surface and volume pairing forces gives the pairing gaps that are compatible with the experimental odd-even mass staggering. Results of the deformed Hartree-Fock-Bogoliubov calculations for this 'mixed' pairing interaction, and using the transformed harmonic oscillator basis, are presented.
