Single fission experiment maps excess gamma rays from more than a dozen unstable nuclei

Physicists have successfully mapped excess gamma-ray emissions from over a dozen unstable nuclei in a single fission experiment. This research provides new insights into the fundamental fission process of heavy atomic nuclei.

Credit: IFJ PAN In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many isotopes produced in nuclear fission marks an important step toward a better understanding of one of the key phenomena in modern nuclear physics: the fission process itself.
