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…
Bound-state Compton scattering of linearly polarized photons
Jonas Sommerfeldt, Nick M. Mayer, Anna Maiorova +4
We present a theoretical study of Compton scattering of X- and -rays by a -shell electron. Special attention is paid to the double-differential cross section and polarizatio…
The Darkfield Approach to Measuring Vacuum Birefringence and Light-by-Light Couplings -- A Proof-of-Principle Experiment
Michal SmÃd, Pooyan Khademi, Carsten Bähtz +29
Vacuum fluctuations give rise to effective nonlinear interactions between electromagnetic fields. These generically modify the characteristics of light traversing a strong-field re…
Schottky detection techniques for ultra-rare short-lived ions in heavy ion storage rings
Shahab Sanjari, Yuri A. Litvinov, George Hudson-Chang +10
Non-destructive Schottky detectors are indispensable devices widely used in experiments at heavy-ion storage rings. In particular, they can be used to accurately determine the mass…
