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 $…
Comparative scintillation performance of EJ-309, EJ-276, and a novel organic glass
T. A. Laplace, B. L. Goldblum, J. E. Bevins +14
An organic glass scintillator developed by Sandia National Laboratories was characterized in terms of its light output and pulse shape discrimination (PSD) properties and compared…
Enhanced production of 60Fe in massive stars
A. Spyrou, D. Richman, A. Couture +23
Massive stars are a major source of chemical elements in the cosmos, ejecting freshly produced nuclei through winds and core-collapse supernova explosions into the interstellar med…
2MASS J06164006-6407194: The First Outer Halo L Subdwarf
M. C. Cushing, D. Looper, A. J. Burgasser +5
We present the serendipitous discovery of an L subdwarf, 2MASS J06164006-6407194, in a search of the Two Micron All Sky Survey for T dwarfs. Its spectrum exhibits features indicati…
Radiative-capture cross sections for the La() reactionusing thermal neutrons and structural properties of La
A. M. Hurst, A. Sweet, B. L. Goldblum +11
A set of prompt partial -ray production cross sections from thermal neutron-capture were measured for the La() reaction using a guided beam of subthermal (thermal…
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.…
