Aluminium-20 shatters nuclear norms with explosive triple-proton breakup
Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through a stunning three-proton emission sequence, shedding light on nuclear behavior far beyond the limits of stability. This breakthrough, involving researchers from China and Germany, not only adds a new isotope to the nuclear chart but also hints at broken symmetry and unexpected quantum properties deep within matter.

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic nuclei. In particular, exotic decay modes like proton emission provide essential spectroscopic tools for probing the structure of nuclei far from the valley of stability—the region containing stable nuclei on the nuclear chart.
