Aluminium-20: The Self-Destructing Atom Scientists Never Saw Coming

Physicists have discovered a never-before-seen atomic nucleus — aluminium-20 — that quite literally falls apart in three distinct proton bursts. This rare and unstable isotope doesn’t just decay, it unravels through a dramatic sequence of proton emissions that challenge long-held assumptions about nuclear structure. The finding marks the first known case of a “triple-proton decay […]
