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.…
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 of…
Microsecond Isomer at the N=20 Island of Shape Inversion Observed at FRIB
T. J. Gray, J. M. Allmond, Z. Xu +63
Excited-state spectroscopy from the first Facility for Rare Isotope Beams (FRIB) experiment is reported. A 24(2)-s isomer was observed with the FRIB Decay Station initiator (FDS…
New isomeric transition in Mg: Bridging the N=20 and N=28 islands of inversion
M. Madurga, J. M. Christie, Z. Xu +20
We observed a new isomeric gamma transition at 168 keV in Mg, with a half-life of T=[130-500] ns. We propose that the observed transiti…
Improved Limit on Tensor Currents in the Weak Interaction from Li Decay
M. T. Burkey, G. Savard, A. T. Gallant +28
The electroweak interaction in the Standard Model (SM) is described by a pure vector-axial-vector structure, though any Lorentz-invariant component could contribute. In this work,…
Beta-delayed-neutron studies of Sb and I performed with trapped ions
B. S. Alan, S. A. Caldwell, N. D. Scielzo +19
Beta-delayed-neutron (n) spectroscopy was performed using the Beta-decay Paul Trap and an array of radiation detectors. The n branching ratios and energy spectra for $^{135,1…
Low-lying level structure of Cu and its implications on the rp process
W-J. Ong, C. Langer, F. Montes +39
The low-lying energy levels of proton-rich Cu have been extracted using in-beam -ray spectroscopy with the state-of-the-art -ray tracking array GRETINA in conjunction…
A measurement of the ionization efficiency of nuclear recoils in silicon
F. Izraelevitch, D. Amidei, A. Aprahamian +26
We have measured the ionization efficiency of silicon nuclear recoils with kinetic energy between 1.8 and 20 keV. We bombarded a silicon-drift diode with a neutron beam to perform…
Scintillation efficiency measurement of Na recoils in NaI(Tl) below the DAMA/LIBRA energy threshold
Jingke Xu, Emily Shields, Frank Calaprice +18
The dark matter interpretation of the DAMA modulation signal depends on the NaI(Tl) scintillation efficiency of nuclear recoils. Previous measurements for Na recoils have large dis…
Measurement of Scintillation and Ionization Yield and Scintillation Pulse Shape from Nuclear Recoils in Liquid Argon
H. Cao, T. Alexander, A. Aprahamian +32
We have measured the scintillation and ionization yield of recoiling nuclei in liquid argon as a function of applied electric field by exposing a dual-phase liquid argon time proje…
