TL;DR
This paper investigates the stability of extremely neutron-rich uranium isotopes using advanced nuclear models, revealing potential stability far beyond previously known neutron numbers, up to around N=258.
Contribution
It introduces predictions of stable uranium isotopes at unprecedented neutron numbers using relativistic and Skyrme models, extending the nuclear landscape.
Findings
Indications of stable isotopes beyond N=184
Predictions of stability up to N≈258
Use of multiple theoretical approaches
Abstract
We study Uranium isotopes and surrounding elements at very large neutron number excess. Relativistic mean field and Skyrme-type approaches with different parametrizations are used in the study. Most models show clear indications for isotopes that are stable with respect to neutron emission far beyond N=184 up to the range of around N=258.
