The Confined beta-Soft rotor model in rare-earth nuclei
Jim A. Papadopoulos, T. J. Mertzimekis, P. Koseoglou +2
Contemporary theoretical descriptions of nuclear structure rely mainly on microscopic, single-particle frameworks often in competition with collective degrees of freedom, especiall…
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…
