Description

Beta-delayed charged particle emission is an excellent tool to study nuclear structure evolution of the most exotic nuclear systems near the proton dripline.
As one approaches the proton dripline from the valley of stability, the Q-value for beta decay increases, while separation energies decrease, allowing for increasingly exotic decay modes.

This talk focuses on beta-delayed two-proton emission (β2p) and beta-delayed alpha emission (βα) of light proton-rich nuclei based on a recent experimental campaign initiated at the Facility for Rare Isotope Beams (FRIB) in the United States.
The mechanism of β2p has the potential to give new fundamental insights into the nuclear interaction, while both β2p and βα are strong spectroscopic instruments in the complex region of the chart of nuclides where they are both active.
The richness of information that can be extracted from the study of the lightest precursor to β2p, 22Al, will be presented, and βα will be used to shed new light on the halo nature of 22Al, which has gained much attention recently as a potential proton-halo nucleus.
