Parameter-free deformation variables of the proxy-SU(3) symmetry in even-even actinide, superheavy and hyperheavy nuclei with Z=82-126, N=82-258
Dennis Bonatsos, V. K. B. Kota, Andriana Martinou +5
Superheavy and hyperheavy nuclei are one of the frontiers of nuclear structure nowadays, while also for many actinides rather limited experimental information exists. Therefore, th…
Parameter-free deformation variables of the proxy-SU(3) symmetry in even-even atomic nuclei with Z=28-82, N=28-126
Dennis Bonatsos, V. K. B. Kota, Andriana Martinou +5
The proxy-SU(3) approximation to the shell model, which restores the SU(3) symmetry of the 3-dimensional harmonic oscillator beyond the sd shell, predicts the collective deformatio…
Triaxial shapes in even-even nuclei: A theoretical overview
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +4
Triaxial shapes in even-even nuclei have been considered since the early days of the nuclear collective model. Although many theoretical approaches have been used over the years fo…
Robustness of the proxy-SU(3) symmetry in atomic nuclei and the role of the next highest weight irreducible representation
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +4
The proxy-SU(3) symmetry predicts, in a parameter-free way, the collective deformation variables beta and gamma in even-even atomic nuclei away from closed shells based on the high…
Preponderance of triaxial shapes in atomic nuclei predicted by the proxy-SU(3) symmetry
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +4
The proxy-SU(3) symmetry predicts, in a parameter-free way, based only on the Pauli principle and the short-range nature of the nucleon-nucleon interaction, non-vanishing values of…
Seven years of the proxy-SU(3) shell model symmetry
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +2
The proxy-SU(3) symmetry was first presented in HINPw4 in Ioannina in May2017, justified within the Nilsson model and applied to parameter-free predictions of the collective variab…
Prolate-oblate shape transitions and O(6) symmetry in even-even nuclei: A theoretical overview
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +2
Prolate to oblate shape transitions have been predicted in an analytic way in the framework of the Interacting Boson Model (IBM), determining O(6) as the symmetry at the critical p…
Shape coexistence in even-even nuclei: A theoretical overview
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +2
The last decade has seen a rapid growth of our understanding of the microscopic origins of shape coexistence, assisted by the new data provided by the modern radioactive ion beam f…
Signatures for shape coexistence and shape/phase transitions in even-even nuclei
Dennis Bonatsos, Andriana Martinou, S. K. Peroulis +2
Systematics of B(E2) transition rates connecting the first excited 0+ state to the first excited 2+ state of the ground state band in even-even nuclei indicates that shape coexiste…
Unified picture of nucleon pairs playing leading roles in nuclear collectivity
Dennis Bonatsos, Andriana Martinou, I. E. Assimakis +3
Proxy-SU(3) symmetry is an approximation scheme extending the Elliott SU(3) algebra of the sd shell to heavier shells. When introduced in 2017, the approximation had been justified…
Connecting the proxy-SU(3) symmetry to the shell model
Dennis Bonatsos, Andriana Martinou, I. E. Assimakis +3
Proxy-SU(3) symmetry is an approximation scheme extending the Elliott SU(3) algebra of the sd shell to heavier shells. When introduced in 2017, the approximation had been justified…
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…
