The Brief
- Researchers searched for double-alpha decay of radium-224 using a GAGG:Ce crystal scintillator.
- The crystal was contaminated with thorium, which was part of the measurement setup.
- The study reports a lower limit on the decay, not a detection.
Why it matters
The result sets a bound on a very rare nuclear decay mode, which constrains theoretical models of nuclear structure and guides future low-background searches.
Who’s affected
