Islands of shape coexistence: theoretical predictions and experimental evidence
Andriana Martinou, Dennis Bonatsos, S. K. Peroulis +3
Parameter-free theoretical predictions based on a dual shell mechanism within the proxy-SU(3) symmetry of atomic nuclei, as well as covariant density functional theory calculations…
Islands of shape coexistence from single-particle spectra in covariant density functional theory
Dennis Bonatsos, K. E. Karakatsanis, Andriana Martinou +2
Using covariant density functional theory with the DDME2 functional and labeling single-particle energy orbitals by Nilsson quantum numbers, a search for particle-hole (p-h) excita…
Islands of shape coexistence in proxy-SU(3) symmetry and in covariant density functional theory
Dennis Bonatsos, K. E. Karakatsanis, Andriana Martinou +2
Shape coexistence in even-even nuclei is observed when the ground state band of a nucleus is accompanied by another K=0 band at similar energy but with radically different structur…
Collective-model description of shape coexistence and intruder states in cadmium isotopes based on a relativistic energy density functional
K. Nomura, K. E. Karakatsanis
Low-energy structure of even-even Cd isotopes is analyzed using a collective model that is based on the nuclear density functional theory. Spectroscopic properties are…
Microscopic origin of shape coexistence in the N=90, Z=64 region
Dennis Bonatsos, K. E. Karakatsanis, Andriana Martinou +2
A microscopic explanation of the nature of shape coexistence in the N=90, Z=64 region is suggested, based on calculations of single particle energies through standard covariant den…
Signatures of shape phase transitions in krypton isotopes based on relativistic energy density functionals
K. E. Karakatsanis, K. Nomura
Spectroscopic properties that characterize the shape phase transitions in krypton isotopes with the mass region are investigated within the framework of the nuclear de…
Highest weight irreducible representations favored by nuclear forces within SU(3)-symmetric fermionic systems
Andriana Martinou, S. Sarantopoulou, K. E. Karakatsanis +1
The consequences of the attractive, short-range nucleon-nucleon (NN) interaction on the wave functions of nuclear models bearing the SU(3) symmetry are reviewed. The NN interaction…
The islands of shape coexistence within the Elliott and the proxy-SU(3) Models
Andriana Martinou, Dennis Bonatsos, T. J. Mertzimekis +5
A novel dual-shell mechanism for the phenomenon of shape coexistence in nuclei within the Elliott SU(3) and the proxy-SU(3) symmetry is proposed for all mass regions. It is suppose…
Why nuclear forces favor the highest weight irreducible representations of the fermionic SU(3) symmetry
Andriana Martinou, Dennis Bonatsos, K. E. Karakatsanis +4
The consequences of the attractive, short-range nucleon-nucleon (NN) interaction on the wave functions of the Elliott SU(3) and the proxy-SU(3) symmetry are discussed. The NN inter…
Spin-orbit splittings of neutron states in isotones from covariant density functionals and their extensions
Konstantinos Karakatsanis, G. A. Lalazissis, Peter Ring +1
Spin-orbit splitting is an essential ingredient for our understanding of the shell structure in nuclei. One of the most important advantages of relativistic mean-field (RMF) models…
