Nuclear shape evolution and shape coexistence in Zr and Mo isotopes

Triaxiality and shape coexistence in Germanium isotopes

The ground-state deformations of the Ge isotopes are investigated in the framework of GognyHartree-Fock-Bogoliubov (HFB) and Skyrme Hartree-Fock plus pairing in the BCS approximation. Three different Skyrme parametrizations are used to explore the influence of different effective masses and spin-orbit models. There is generally good agreement for binding energies and deformations (total quadrup...

The role of shell evolution in shape coexistence

We first review the shell evolution in exotic nuclei driven by nuclear forces. We then demonstrate that the underlying mechanism played by the balance of the tensor and central components in the effective nucleon–nucleon interaction is crucial when describing shape coexistence. This effect will be referred to as type II shell evolution, while the shell evolution passing through a series of isot...

evolution of shape in late islamic seals

shape is regarded as one of outward characteristics of islamic seals. this characteristic, which is part of common traits of all different areas of seal studies, could be defined as framework of circumference of seals impression on written materials and documents, which in fact results from the shape of seals surfaces. shape has been considered as one of the ways of recognizing the administrati...
