Direct Mass Measurements to Inform the Behavior of ^128m$$\mathrm{Sb}$$ in Nucleosynthetic Environments

Journal Article Hoff, D. E. M. ; Kolos, K. ; Misch, G. W. ; ... - Physical Review Letters

Nuclear isomer effects are pivotal in understanding nuclear astrophysics, particularly in the rapid neutron-capture process where the population of metastable isomers can alter the radioactive decay paths of nuclei produced during astrophysical events. The β-decaying isomer ^128mSb was identified as potentially impactful since the β-decay pathway along the A = 128 isobar funnels into this state bypassing the ground state. Here we report the first direct mass measurements of the ¹²⁸Sb isomer and ground state using the Canadian Penning Trap mass spectrometer at Argonne National Laboratory. We find mass excesses of -84564.8(25) keV and -84608.8(21) keV, respectively, resulting in anmore »« less

Crossing N = 28 Toward the Neutron Drip Line: First Measurement of Half-Lives at FRIB

Journal Article Crawford, H. L. ; Tripathi, V. ; Allmond, J. M. ; ... - Physical Review Letters

Here, new half-lives for exotic isotopes approaching the neutron drip-line in the vicinity of N~28 for Z=12–15 were measured at the Facility for Rare Isotope Beams (FRIB) with the FRIB decay station initiator. The first experimental results are compared to the latest quasiparticle random phase approximation and shell-model calculations. Overall, the measured half-lives are consistent with the available theoretical descriptions and suggest a well-developed region of deformation below ⁴⁸Ca in the N=28 isotones. The erosion of the Z=14 subshell closure in Si is experimentally confirmed at N=28, and a reduction in the ³⁸Mg half-life is observed as compared with itsmore »« less

Direct-drive measurements of laser-imprint-induced shock velocity nonuniformities [First direct-drive measurements of laser-imprint-induced shock velocity nonuniformities]

Journal Article Peebles, J. L. ; Hu, S. X. ; Theobald, W. ; ... - Physical Review E

Perturbations in the velocity profile of a laser-ablation-driven shock wave seeded by speckle in the spatial beam intensity (i.e., laser imprint) have been measured. Direct measurements of these velocity perturbations were recorded using a two-dimensional high-resolution velocimeter probing plastic material shocked by a 100-ps picket laser pulse from the OMEGA laser system. The measured results for experiments with one, two, and five overlapping beams incident on the target clearly demonstrate a reduction in long-wavelength (>25–μm) perturbations with an increasing number of overlapping laser beams, consistent with theoretical expectations. Furthermore, these experimental measurements are crucial to validate radiation-hydrodynamics simulations of lasermore »« less

Combined Measurement of the Higgs Boson Mass in $p p$ Collisions at $\sqrt{s} = 7$ and 8 TeV with the ATLAS and CMS Experiments

Journal Article Aad, G. ; Abbott, B. ; Abdallah, J. ; ... - Physical Review Letters

A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4 decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual channels and the two experiments are found to be consistent among themselves. The combined measured mass of the Higgs boson is mH=125.09±0.21 (stat)±0.11 (syst) GeV.
