Precision masses of neutron-rich platinum and gold nuclei reveal enhanced shell strength below doubly-magic Pb
David Freire-Fernández, Rui-Jiu Chen, Usama Ahmed +63
The heaviest stable nuclei in the universe owe their existence to quantum shell structure, the grouping of protons and neutrons into discrete energy levels separated by gaps. The l…

High-temperature Tl decay clarifies Pb dating in early Solar System
G. Leckenby, R. S. Sidhu, R. J. Chen +56
Radioactive nuclei with lifetimes on the order of millions of years can reveal the formation history of the Sun and active nucleosynthesis occurring at the time and place of its bi…
