The experiment, led by the University of Surrey (UK) in collaboration with the Facility for Rare Isotope Beams (FRIB) and Lawrence Berkeley National Laboratory (LBNL), took place at FRIB in Michigan, USA, using the newly delivered Gamma-Ray Energy Tracking Array (GRETA). Led by LBNL’s Nuclear Science Division and delivered by a collaboration with Argonne National Laboratory, Oak Ridge National Laboratory and FRIB, GRETA is a $58 million detector designed to reveal the structure of atomic nuclei in unprecedented detail.
