摘要:
Symmetry-unrestricted Hartree-Fock-Bogoliubov calculations with finite-range density-dependent Gogny force are presented with a triaxial harmonic oscillator basis. We include all the contributions to the paring and Hartree-Fock potentials arising from Gogny and Coulomb interaction as well as the center of mass correction. Ground-state properties are calculated for C, O and Ne isotopes, and compared with available experiment, Hartree-Fock plus BCS, shell model and Relativistic-Hartree-Bogoliubov calculations. We show that predicted drip lines are strongly model dependent due to their sensitivity to various theoretical details. Shape coexistence phenomenon is discussed. ©2001 American Institute of Physics.

摘要:
We suggest a new class of isomeric states in nuclei. By study the mixed symmetry states in the framework of the neutron-proton interacting boson model(IBM2), it is found that some of the mixed symmetry states with moderate high spins change very fast with respect to the Majorana interaction. Under certain conditions, they become the yrast state or yrare state. These states are difficult to decay and become very stable. This study suggests that a possible new mode of isomers may exists due to the special nature in their proton and neutron degrees of freedom. ©2001 American Institute of Physics.
