9. Halo orbits and the nuclear radius

Invited (In person)

The nuclear radius is one of the fundamental properties of the atomic nucleus. While the direct measurement is not always possible, one can infer its size by measuring other observables.
Recent theoretical studies by Bonnard and collaborators have put in evidence the role of the large radius of low-l orbits in a main nuclear shell in determining the nuclear radius and its evolution when...

43. Comparison of bulk and interfacial diffusion of $^{8}\mathrm{Li}^{+}$ in solid-state battery materials with $\beta$-NMR at VITO

Invited (In person)

Solid-state battery (SSB) technology presents a transformative alternative to conventional liquid-state batteries, addressing many of their inherent weaknesses. However, current SSB materials are limited by poor charge-discharge rates, primarily due to restricted ion diffusion and low conductivity across buried interfaces. Conventional characterization and ion diffusion measurements focus...

5. Stable triaxial rotation as the main mode of excitation at or around magic numbers

Submitted oral (In person)

Here I will present our new experimental and theoretical work on nuclear shapes based on electric quadrupole (E2) matrix elements. New beam development and experimental facilities funded through the GAMKA project have allowed the precise determination of E2 matrix elements at iThemba LABS [1,2]. The large oblate deformation determined in 60Ni is is inconsistent with the near-zero quadrupole...

71. Exploring shape coexistence across N=60 in Sr isotopes using IDS

The region around N≈60 with Z≤40 has generated considerable interest as it features the most abrupt shape transition known to date in the nuclear chart, when crossing from N=58 to N=60 [1]. This transition is closely linked to shape coexistence [2], a phenomenon where two or more states with different intrinsic shapes coexist within the same nucleus at low excitation energy and within a narrow...

25. Investigation of coexisting structures in $^{182}$Pt via detailed $\beta$-decay studies of $^{182}$Au

Jozef Mišt (Comenius University (SK))

Submitted oral (In person)

Gold and platinum nuclei near the $N$ = 104 mid-shell, such as $^{182}$Au and $^{182}$Pt, have attracted considerable interest due to rapid changes in ground-state deformation compared to heavier isotopes. Additionally, a coexistence of at least two configurations, a weakly oblate and a prolate, has been observed for platinum isotopes in this region [1,2]. These phenomena have been extensively...
