High-Precision Mass Measurements of 52Ni and 51Co Reveal Breakdown of the Isobaric Multiplet Mass Equation in the f p Shell
F. M. Maier, G. Bollen, B. A. Brown +10
We performed high-precision mass measurements of the proton-rich nuclei Ni and Co with the LEBIT Penning trap at the Facility for Rare Isotope Beams (FRIB). For $^{52…
Nuclear charge radii of aluminium isotopes at the proton drip line
Alex Brinson, Brooke Rickey, Pierre Arthuis +35
Understanding the evolution of nuclear size away from stability remains a central challenge in nuclear physics. In neutron-deficient systems, charge radii can be highly sensitive t…
The mass of Sn and Bayesian extrapolations to the proton drip line
Christian M. Ireland, Georg Bollen, Scott E. Campbell +23
The favorable energy configurations of nuclei at magic numbers of neutrons and protons are fundamental for understanding the evolution of nuclear structure. The ${Z=50}…
High-precision Penning trap mass measurements of neutron-rich chlorine isotopes at the N=28 shell closure
H. Erington, G. Bollen, G. Dykstra +9
Although it is known that the spherical shell closure erodes, the strength of the closure with decreasing proton number is an open question in nuclear structure. In t…
Exploring Isospin Symmetry Breaking in Exotic Nuclei: High-Precision Mass Measurement of 23Si and Shell-Model Calculations of T = 5/2 Nuclei
F. M. Maier, G. Bollen, B. A. Brown +9
We present a high-precision mass measurement of the proton-rich nucleus 23Si, performed with the LEBIT Penning trap at the Facility for Rare Isotope Beams (FRIB) utilizing the time…
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…
