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 $1…

Constraining nucleon effective masses with flow and stopping observables from the SRIT experiment

C. Y. Tsang, M. Kurata-Nishimura, M. B. Tsang +52

Properties of the nuclear equation of state (EoS) can be probed by measuring the dynamical properties of nucleus-nucleus collisions. In this study, we present the directed flow ($v…

Strong evidence for 9N and the limits of existence of atomic nuclei

R. J. Charity, J. Wylie, S. M. Wang +21

The boundaries of the Chart of Nuclides contain exotic isotopes that possess extreme proton-toneutron asymmetries. Here we report on strong evidence of 9N, one of the most exotic p…

Using spin alignment of inelastically-excited fast beams to make spin assignments: the spectroscopy of 13O as a test case

R. J. Charity, T. B. Webb, J. M. Elson +23

Excited states in 13O were investigated using inelastic scattering of an E/A=69.5-MeV 13O beam off of a 9Be target. The excited states were identified in the invariant-mass spectra…

Probing the Symmetry Energy with the Spectral Pion Ratio

J. Estee, W. G. Lynch, C. Y. Tsang +60

Many neutron star (NS) properties, such as the proton fraction within a NS, reflect the symmetry energy contributions to the Equation of State that dominate when neutron and proton…
