New TechnologiesScientists Create Ultra-Rare Hydrogen-6 Isotope, Defying Nuclear Physics Posted on May 11, 2025 by Administrator Researchers from the A1 Collaboration at the Institute of Nuclear Physics, Johannes Gutenberg University Mainz (JGU), in partnership with scientists from China and Japan, have successfully produced hydrogen-6, one of the most neutron-rich isotopes, using electron scattering for the first time. Conducted at the spectrometer facility of the Mainz Microtron (MAMI) particle accelerator, the experiment introduces a novel approach to studying light, neutron-rich nuclei.
