100. Shaking up the Periodic Table with Superheavy Element Molecules

Jennifer Pore (Lawrence Berkeley National Laboratory)

2026-07-29, 9:00 a.m.

Invited speakers

The Periodic Table is a cornerstone of chemistry, but its validity is challenged by the extreme properties of superheavy elements (SHEs, Z ≥ 104) and actinides (Z > 88). Relativistic effects, stemming from their large nuclear masses, significantly alter their chemical behaviors, potentially limiting the predictive power of the Periodic Table. Recent breakthroughs have provided insights into...

46. Hyperfine spectroscopy of the $K=8^-$ isomer in $^{254}$No with JetRIS resolving a 20-year-old debate

Fedor Ivandikov (KU Leuven)

2026-07-29, 9:30 a.m.

Contributed Talks

Modern nuclear structure studies in the heavy-element region combine state-of-the-art experimental techniques with advanced theoretical models [1,2]. This interplay between experiment and theory not only enhances the interpretation of experimental data but also drives the refinement of theoretical approaches, underscoring the importance of benchmarking models against independent experimental...

149. Laser spectroscopy of heavy actinides

Sebastian Raeder

2026-07-29, 9:50 a.m.

Contributed Talks

The heaviest elements are of interest to nuclear and atomic physicists due to their peculiar properties. While nuclear shell structure effects are responsible for their very existence stabilizing them against spontaneous disintegration, the structure of their electronic shells is affected by strong relativistic effects leading to different atomic and chemical properties compared to their...

129. In-beam $\gamma$-ray spectroscopy of $^{249,251}$Md

Corrigan Appleton (LBNL)

2026-07-29, 10:10 a.m.

Contributed Talks

In-beam γ-ray spectroscopy experiments on the heavy odd-Z nuclei $^{249}$Md and $^{251}$Md were performed at the ATLAS accelerator facility of Argonne National Laboratory using the $^{203}$Tl($^{48}$Ca, 2n) and $^{205}$Tl($^{48}$Ca, 2n) fusion evaporation reactions, respectively. In both experiments the Argonne Gas-Filled Analyzer (AGFA) was used to separate recoils of interest, while...
