Nuclear physicists have experimentally confirmed the existence of the tetraneutron, a meta-stable nuclear system that can decay into four free neutrons. Researchers have predicted the tetraneutron’s existence since 2016. The new results, which agree with predictions from supercomputer simulations, will help scientists understand atomic nuclei, neutron stars, and other neutron-rich systems.
