A Question of Shape: New Mechanism Governing Superheavy Nuclei Survival
A. Rahmatinejad, T. M. Shneidman, G. G. Adamian +3
We demonstrate that hot superheavy nuclei do not retain spherical shapes, as traditionally assumed, but instead equilibrate in deformed, often oblate or triaxial, configurations at…
Survival of Pairing Correlations and Shell Effects at Scission in Finite-Temperature Nuclear Fission: Implications for Odd-Even Staggering
K. Pomorski, A. Augustyn, T. Cap +4
We investigate the finite-temperature evolution of microscopic free-energy corrections in nuclear fission, focusing on pairing and shell effects near scission. The analysis is base…
Static Fission Properties of Even-Even Actinides within the Warsaw Macroscopic-Microscopic Model Using Fourier-over-Spheroid Parameterization
A. Augustyn, T. Cap, R. Capote +2
A systematic study of fission barrier heights and static properties of even-even actinide nuclei from Th to Cf has been performed within the Warsaw macroscopic-microscopic model us…
Paths to Superheavy Nuclei
K. Godbey, F. M. Nunes, M. Albertsson +16
This document summarizes the discussions and outcomes of the Facility for Rare Isotope Beams Theory Alliance (FRIB-TA) topical program "The path to Superheavy Isotopes" held in Jun…
Candidates for three-quasiparticle -isomers in even-odd Fm-Cn nuclei
P. Jachimowicz, M. Kowal, J. Skalski
Following our study of possible -isomers in odd-even Md-Rg nuclei, here we continue with searching for three-quasiparticle 12 and 3 isomer candidates in even-odd Fm…
Demystifying the fusion mechanism in heavy-ion collisions: A six-dimensional Langevin dissipative dynamics approach
Yannen Jaganathen, MichaÅ Kowal, Krzysztof Pomorski
We present an in-depth investigation of heavy-ion fusion dynamics using a six-dimensional Langevin framework that enables unrestricted motion of the asymmetry parameter. The stocha…
