A ground state Al halo is unlikely
E. A. M. Jensen, J. S. Nielsen, B. S. O. Johansson +13
We report the decisive resolution of the ground state spin and parity of the proton-dripline nucleus Al, a prime candidate for a proton halo. The resolution stems from the f…
STIS Cycle 30 Calibration Programs
D. Welty, R. Bohlin, J. Carlberg +8
We discuss the suite of STIS calibration programs executed during HST Cycle 30, covering the period 2022 Nov 07 through 2023 Nov 05. For each of the 19 current regular calibration…
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 (FD…
Constraining the P(S reaction rate in ONe novae via the weak, low-energy, -delayed proton decay of Cl
T. Budner, M. Friedman, C. Wrede +20
The PS reaction plays an important role in understanding nucleosynthesis of nuclides in oxygen-neon novae. The Gaseous Detector with Germanium Taggin…
Extension of the particle x-ray coincidence technique: The lifetimes and branching ratios apparatus
L. J. Sun, J. Dopfer, A. Adams +11
The particle x-ray coincidence technique (PXCT) was originally developed to measure average lifetimes in the ~s range for proton-unbound states populated by elec…
Time Projection Chamber for GADGET II
Ruchi Mahajan, T. Wheeler, E. Pollacco +17
Background: The established GADGET detection system, designed for measuring weak, low-energy -delayed proton decays, features a gaseous Proton Detector with MICROMEGAS readout…
$β^{+}$ Gamow-Teller strengths from unstable O via the reaction in inverse kinematics
S. Giraud, J. C. Zamora, R. Zegers +24
For the first time, the reaction was successfully used in inverse kinematics to extract the Gamow-Teller transition strength in the $β^{+}$ direction from an u…
