Astrophysical significance of the isomer Ag demonstrated through direct mass measurement
F. Rivero, M. Brodeur, J. A. Clark +18
The abundance of elements heavier than iron produced via the astrophysical rapid-neutron capture process depends sensitively on the atomic mass of the involved nuclei as well as th…

Investigating the effects of precise mass measurements of Ru and Pd isotopes on machine learning mass modeling
W. S. Porter, B. Liu, D. Ray +19
Atomic masses are a foundational quantity in our understanding of nuclear structure, astrophysics and fundamental symmetries. The long-standing goal of creating a predictive global…

Nuclear uncertainties associated with the ejecta of a neutron-star black-hole accretion disk
M. R. Mumpower, T. M. Sprouse, J. M. Miller +5
The simulation of heavy element nucleosynthesis requires input from yet-to-be-measured nuclear properties. The uncertainty in the values of these off-stability nuclear properties p…
