Precision masses of neutron-rich platinum and gold nuclei reveal enhanced $N = 126$ shell strength below doubly-magic $^{208}$ Pb

David Freire-FernÃ¡ndez, 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…

Direct observation of $I^^{2}$ and $I^^{3}$ decay from a high-spin long-lived isomer in $^{187}$ Ta

J. L. Chen, H. Watanabe, P. M. Walker +20

$^{187}$ Ta ( $Z = 73$ , $N = 114$ ) is located in the neutron-rich $A \approx 190$ region where a prolate-to-oblate shape transition via triaxial softness is predicted to take place. A pr…
