The findings reveal that ⁶H possesses a lower ground-state energy than many recent theories predicted.
This suggests that the interactions between the multiple neutrons within this extremely unstable nucleus are stronger than expected, which prompts a re-evaluation of multi-nucleon forces in very neutron-rich environments.
The experiment was a collaborative effort involving the A1 Collaboration at the Institute of Nuclear Physics at JGU, alongside scientists from Fudan University in Shanghai, China, Tohoku University Sendai, and the University of Tokyo in Japan.
