In a recent paper in Nature Physics, an international research collaboration, including Edward G. Bilpuch Distinguished Professor Robert Janssens as a co-PI for the experiment, used world-class instrumentation at the Facility for Rare Isotope Beams (FRIB) to study the rare isotope chromium-62. Researchers used a gamma-ray spectroscopy experiment in tandem with theoretical models to identify an unexpected variety of shapes in chromium-62. The finding provides more insight into islands of inversion. (Graphic courtesy of the Facility for Rare Isotope Beams)
