Description of superdeformed bands in light N = Z nuclei using the cranked Hartree-Fock-Bogoliubov method
نویسنده
چکیده
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 following points: cross-shell excitations in the sd and pf shells; the role of the g9/2 and d5/2 orbitals; the effect of nuclear pairing; and the interplay between triaxiality and band termination.

Cranked Relativistic Hartree - Bogoliubov Theory : Formalism and Application to the Superdeformed Bands in the A ∼ 190 region
Cranked Relativistic Hartree-Bogoliubov theory without and with approximate particle number projection by means of the Lipkin-Nogami method is presented in detail as an extension of Relativistic Mean Field theory with pairing correlations to the rotating frame. Pairing correlations are taken into account by a finite range two-body force of Gogny type. The applicability of this theory to the des...

A parameter free investigation of the moments of inertia of ground state rotational bands in well deformed rare-earth nuclei is carried out using Cranked Relativistic Hartree-Bogoliubov (CRHB) and non-relativistic Cranked Hartree-Fock-Bogoliubov (CHFB) theories. In CRHB theory, the relativistic fields are determined by the non-linear Lagrangian with the NL1 force and the pairing interaction by ...

A systematic investigation of the yrast superdeformed (SD) rotational bands in even-even nuclei of the A ∼ 190 mass region has been performed within the framework of the cranked relativistic Hartree-Bogoliubov theory. The particle-hole channel of this theory is treated fully relativistically, while a finite range two-body force of Gogny type is used in the particle-particle (pairing) channel. U...
