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…

Half-life determination of heavy ions in a storage ring considering feeding and depleting background processes

R. J. Chen, G. Leckenby, R. S. Sidhu +49

Heavy-ion storage rings have relatively large momentum acceptance which allows for multiple ion species to circulate at the same time. This needs to be considered in radioactive de…

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…

Measurement of the Isolated Nuclear Two-Photon Decay in

D. Freire-Fernández, W. Korten, R. J. Chen +57

The nuclear two-photon or double-gamma () decay is a second-order electromagnetic process whereby a nucleus in an excited state emits two gamma rays simultaneously. To be able…
