Beta decay of potassium-54 reveals the role of two-body currents in neutron-rich nuclei
Zhengyu Xu, Robert Grzywacz, Matthias Heinz +84
The beta decay of neutron-rich nuclei probes the microscopic nature of weak interactions in the nuclear medium under extreme conditions. Such weak decays drive the synthesis of hea…

Beta-decay Half Lives beyond Ca: A Systematic Survey of Decay Properties approaching the Neutron Dripline
W. -J. Ong, Z. Y. Xu, R. Grzywacz +83
In an experiment performed at the Facility for Rare Isotope Beams (FRIB) using the FRIB Decay Station initiator (FDSi), 15 new half lives of isotopes near Ca were measured.…

Modeling of Light Production in Inorganic Scintillators
B. Kreider, I. Cox, R. Grzywacz +25
In recent experiments, inorganic scintillators have been used to study the decays of exotic nuclei, providing an alternative to silicon detectors and enabling measurements that wer…
