Contact Pairing Interaction for the Hartree- Fock-bogoliubov Calculations
Properties of density-dependent contact pairing interactions in nuclei are discussed. 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 tra...
متن کاملHartree-fock-bogoliubov for Deformed Neutron-rich Nuclei
The two-basis method to solve the HFB for deformed nuclei in coordinate space is examined concerning the precision of the density tail. Small cutoff energies are shown to give rise to ripples in the tail, whose wave length corresponds to the cutoff momentum. More precise solutions require higher cutoff energies, which result in HFB matrices of larger dimensions. To circumvent the difficulty of ...
متن کاملHartree-Fock-Bogoliubov Calculations in the UCOM Framework
With the advent of new radioactive beam facilities like FAIR, the structure of exotic nuclei far beyond the valley of stability can be probed experimentally, providing a strong motivation for theoretical studies using ab initio approaches and interactions which provide a stringent link to QCD as the fundamental theory of the strong interaction. To this end, we apply second-generation VUCOM inte...
متن کامل1 Symmetry - Unrestricted Skyrme - Hartree - Fock - Bogoliubov Calculations for Exotic Shapes in N = Z Nuclei from 64 Ge to 84
By performing fully 3D symmetry-unrestricted Skyrme-Hartree-FockBogoliubov calculations, we discuss shape coexistence and possibility of exotic deformations simultaneously breaking the reflection and axial symmetries in proton-rich N = Z nuclei: Ge, Se, Kr, Sr, Zr and Mo. Results of calculation indicate that the oblate ground state of Se is extremely soft against the Y33 triangular deformation,...
متن کاملDescription of superdeformed bands in light N = Z nuclei using the cranked Hartree-Fock-Bogoliubov method
Superdeformed states in light N = Z nuclei are studied by means of the self-consistent cranking calculation (i.e., the P+QQ model based on the cranked Hartree-Fock-Bogoliubov method). Analyses are given for two typical cases of superdeformed bands in the A 40 mass region, that is, bands where backbending is absent (40Ca) or present (36Ar). Investigations are carried out particularly for the fol...
