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…
Proxy-SU(3) symmetry in the shell model basis
Andriana Martinou, Dennis Bonatsos, N. Minkov +4
The proxy-SU(3) symmetry has been proposed for spin-orbit like nuclear shells using the asymptotic deformed oscillator basis for the single particle orbitals, in which the restorat…
Parameter-free predictions for the collective deformation variables beta and gamma within the pseudo-SU(3) scheme
Dennis Bonatsos, Andriana Martinou, S. Sarantopoulou +3
The consequences of the short range nature of the nucleon-nucleon interaction, which forces the spatial part of the nuclear wave function to be as symmetric as possible, on the pse…
Breaking SU(3) spectral degeneracies in heavy deformed nuclei
Dennis Bonatsos, I. E. Assimakis, Andriana Martinou +3
Symmetries are manifested in nature through degeneracies in the spectra of physical systems. In the case of heavy deformed nuclei, when described in the framework of the Interactin…
Connection between Elliott SU(3) and spherical shell model bases
A. Martinou, N. Minkov, S. Sarantopoulou +3
In the Elliott SU(3) symmetry scheme the single particle basis is derived from the isotropic harmonic oscillator Hamiltonian in the Cartesian coordinate system. These states are tr…
