Rapid structural evolution of neutron-rich silicon isotopes toward N = 28
G. L. Zimba, H. Iwasaki, B. A. Brown +27
Neutron-rich Si isotopes represent a unique case of shell evolution, exhibiting a robust shell closure at and pronounced quadrupole collectivity at . We report lifet…
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.…
Universal Effective Charges in the and Shells
T. H. Ogunbeku, J. M. Allmond, T. J. Gray +79
The 247-keV state in Sc, populated in the decay of Ca, is reported here as a nanosecond isomer with a half-life of 26.0(22) ns. The state is interpreted as the $…
The evidence of shell closure and -delayed neutron emission from F
J. F. Peltier, Z. Y. Xu, I. Cox +16
We measured the -delayed neutron emission from F for the first time at the Facility for Rare Isotope Beams (FRIB). Using combined neutron and -ray detector systems o…
