Nuclear deformation has been a topic of interest for many decades. While most nuclei can be described using only quadrupole deformation, recent experimental results [1, 2], in agreement with theoretical predictions [3, 4], indicate that a more exotic type of deformation, namely octupole deformation, is needed to best describe nuclei in certain regions of the nuclear chart. In particular, the...

In the transfermium region (Z $\geq 100$), spontaneous fission (SF) is a prominent decay mode, often competing with alpha and beta decay. However, experimental measurements remain challenging for most super-heavy nuclei (SHN) due to their low production cross-section. Stability against SF is governed by the fission barrier, which is strongly influenced by shell effects [2]. Hence, studies of...

The synthesis of superheavy nuclei (SHN) in heavy-ion fusion-evaporation reactions is governed by a delicate interplay between two competing effects. On one hand, the capture and fusion cross section rises with the bombarding energy as the projectile overcomes the Coulomb barrier and the dinuclear system evolves toward a compound nucleus. On the other hand, the survival probability of the...

The GANIL accelerator complex in Caen (France) recently commissioned a new superconducting linear accelerator as part of the SPIRAL2 facility. This facility enables the production of heavy and super-heavy radionuclides via fusion-evaporation reactions at the entrance of the Super Separator Spectrometer (S$^{3}$) experimental area. There, the secondary...

In the last decade Multi-Reflection Time-of-Flight Mass-Spectrometers (MR-ToF-MS) [1] have been established as integral parts of radioactive ion beam facilities. These devices are used to separate and to measure the atomic masses of particularly exotic, short-lived radioactive nuclei to high precision, shedding light on the nuclear forces [2], the composition of neutron stars [3], and the...

Optical spectral lines serve as unique fingerprints for the elements and provide the most precise means to study their electronic structure, as well as reveal properties of atomic nuclei. Atomic spectroscopy has been advancing towards ever heavier atomic species, with superheavy elements (SHE) being of particular interest due to their role in understanding nuclear stability at the top of the...

Andres Felipe LOPEZ (PhD GANIL CNRS)24/09/2026 12:50Heavy & Superheavy nucleiOral Presentation
Laser spectroscopy for studying the ground- and isomeric-state properties of exotic nuclei has established itself as a versatile and powerful tool, capable of providing access to nuclear-model-independent data such as mean-square charge radii, magnetic dipole and electric quadrupole moments, and nuclear spins [1]. For resonance ionization spectroscopy, a critical set of conditions is having...
