Neutron‐deficient nuclei around mass number A~80 are of great interest in nuclear structure and nuclear astrophysics (this region, e.g., is explored in the rp‐process nucleosynthesis). Although shape‐coexistence is becoming a rather common feature along the nuclear chart [1], the region of medium‐mass N~Z nuclei is expected to show several collective structures associated to distinctive shapes...
In April 2022, AGATA, the European Ge-array at the forefront of gamma detection technology [1,2] was installed at LNL. Based on the new concept of gamma-ray tracking, it can identify the gamma interaction points (pulse shape analysis) and reconstruct via software the trajectories of the individual photons (gamma-ray tracking). Shortly thereafter a physics campaign has started using stable...
I shall discuss the meaning of the "nuclear shape" in the laboratory frame proper to the Spherical Shell Model, and the
algebraic models that make its foundations.
Shape coexistence, shape mixing and shape entanglement will be illustrated with relevant physics cases, In particular
I shall show that shape coexistence acts as a portal to the Islands of Inversion at
at N=20-28 and N=40-50...
The dynamics of nuclei with a triaxial core and a non-axial rigid quasiparticle alignment is described in a semiclassical setting [1,2]. This includes the investigation of the spin dependence of the stationary points and the derivation of the existence conditions for distinct dynamical phases. Additionally, an intuitive visualization of the classical orbits is used to show the classical motion...
There is an increasing interest in exotic symmetries predicted to occur in atomic nuclei, yet in the past traditionally associated with molecular structures. This tendency is witnessed by growing number of publications in this domain. Tetrahedral and octahedral symmetries can be considered among the most exotic since they are predicted to produce 4-fold degeneracies of the nucleonic levels in...
