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 ...
For decades, scientists have puzzled over why certain atomic nuclei unexpectedly produce large numbers of low-energy gamma rays. A new experiment traced the effect to magnetic changes inside the ...
A physicist wants to collide matter with antimatter to test a radical idea: information may be a physical component of the ...
Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus. The breakthrough could improve models of how stars, supernovae, and neutron ...
Under construction at Berkeley Lab, the Gamma-Ray Energy Tracking Array, or GRETA, is a cutting-edge instrument for nuclear physics. Software developed at ORNL will enable GRETA to send data to the ...
Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...
