A team of researchers from the RIKEN Nishina Center for Accelerator-Based Science in Japan has demonstrated that the magic numbers 20 and 28 disappear from all neutron-rich magnesium isotopes, thereby establishing a new, larger area of nuclear deformation in the nuclear chart.
The Japanese study, published today in the prestigious journal Physical Review Letters, was made possible by the intense beam at the Radioactive Beam Factory (RIBF) at RIKEN, which produces the most intense radioactive isotope beams in the world.
