Collinear Laser Spectroscopy on Neutron-Deficient Al Isotopes

ORAL

Abstract

A large reaction cross section [1] in 23Al and a large isospin asymmetry in the mass A=22 system [2] of 22Al suggest their proton halo structures. However, the last proton presumably occupies the d5/2 orbital in the ground state, making the proton halo structures’ existence not decisive. In an upcoming experiment at the BECOLA facility at FRIB, charge radii and electromagnetic moments will be determined through isotope shift measurements to directly address the proton distributions in 22, 23Al. The newly commissioned Resonance Ionization Spectroscopy Experiment (RISE) setup will be used for laser spectroscopy. The experimental detail will be discussed, as well as the commissioning of RISE.
