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…
Mass spectrometry of Zn ground and isomeric states from in-trap decay of Cu
M. Müller, N. A. Althubiti, D. Atanasov +14
We report on high-precision mass measurements of the ground and first isomeric state of Zn, performed using the time-of-flight ion-cyclotron-resonance technique at the ISOLT…
Mass measurements of Yb identify an anomalous proton-neutron interaction
C. L. Brown, J. Ash, B. Ashrafkhani +30
Mass measurements of nuclei can identify structurally-driven trends in binding energy across isotopic chains, and can also isolate specific nucleon-nucleon interactions, such as th…
Octupole deformation in quasiparticle states of odd-mass and odd-odd nuclei
N. Kontowicz, L. Bonneau, J. Bartel +3
As a follow up of [Phys. Scr. 99 055305 (2024)], where we studied axial octupole shapes in two-quasiparticle states of even-even nuclei, we investigate this type of shapes in odd-m…
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…
