For years, the ratio of uranium’s two long-lived isotopes, U-235 and U-238, has been considered invariant, despite measurements made in the mid-1970s that hinted otherwise. Now, with improved precision from state-of-the-art instrumentation, researchers at the University of Illinois unequivocally show this ratio actually does vary significantly in Earth materials.

An international collaboration at the Michigan State University National Superconducting Cyclotron Laboratory (NSCL) has demonstrated a new technique for studying particles traveling at one-third the speed of light. The result, which will be published in Physical Review Letters, opens up new doors to investigating rare isotopes.
