Physicists Start to Pin Down How Stars Forge Heavy Atoms
The Facility for Rare Isotope Beams (FRIB) may not glitter quite like the night sky, plunked as it is between Michigan State University’s chemistry department and the performing arts center. Inside, though, the lab is teeming with substances that are otherwise found only in stars. Here, atomic nuclei accelerate to half the speed of light, smash into a target and shatter into smithereens. The collisions create some of the same rare, unstable isotopes that arise inside stars and which, through a
