Investigating the Possible Halo Structure in 23Al and 22Al
Moving towards the driplines of the nuclear chart, unique structures and phenomena occur, including largely enhanced nucleon distributions referred to as halo nuclei. Understanding these unique nuclei is important to unveil driving nuclear forces and develop nuclear theory. Although neutron halos are commonly observed close to the neutron dripline for light-mass nuclei, proton halos are much rarer due to the Colomb barrier for protons to penetrate. Contrasting conclusions regarding halo structure in 23Al and 22Al have demonstrated a need for a direct measurement of the proton distribution. A large reaction cross section [1] and a large isospin asymmetry in the mass A = 22 system [2] suggest proton halo structures in 23Al and 22Al, respectively. However, the last proton presumably occupies the d5/2 orbital and thus a large centrifugal barrier in the ground state, making the proton halo structures’ existence not decisive. For this purpose, A laser spectroscopy experiment on 22, 23Al, at the BEam COoling LAser spectroscopy (BECOLA) facility using the newly commissioned Resonant Ionization Spectroscopy Experiment (RISE) instrument at the Facility for Rare Isotope Beams (FRIB) was run. The charge radii, spins, and electromagnetic moments were determined through measurements of hyperfine structure and their isotope shifts to directly address the proton distribution and ground state structures in 22, 23Al. The details and results of the BECOLA experiment will be discussed.Today @ 3:45 pm | Cyclotron Institute, 228

Asymmetry Amplification by a Phase Transition Condensed Matter
Nikolai Sinitsyn, LANL
Feb 7 @ 4:00 pm | Mitchell Institute (MIST), MIST 102
Dr. Alexey Belyanin joins researchers from Rice University in a $1.2 million project funded by the W.M. Keck Foundation. The team is leveraging super-radiance, a quantum phenomenon, to develop brighter, faster imaging tools for super-resolution imaging and single-molecule tracking. This work may bring breakthroughs in biology, nanotechnology, and other fields.
