Our recent letter entitled “Probing the Shell Effects on Fission: The New Superheavy Nucleus ²⁵⁷Sg” (P. Mosat et al., Phys. Rev. Lett. 134, 232501 (2025)) has been selected and included in the Physical Review Letters Collection of the Year 2025. This collection highlights a selection of particularly significant and high-impact papers published during the year across all fields of physics. In our field of nuclear physics, only three papers were selected.
The recognition follows a series of our works on the nuclear structure of superheavy nuclei at the gas-filled recoil separator TASCA. Within this successfully ongoing physics program carried out in the SHE Chemistry department, two letters were published in 2025: the above-mentioned study on ²⁵⁷Sg and the discovery of the shortest-lived superheavy nucleus, ²⁵²Rf (J. Khuyagbaatar et al., Phys. Rev. Lett. 134, 022501 (2025)). Both letters were highlighted as Editor’s Suggestions, and the latter was additionally featured in Physics.
