The report of a successful experiment at the new radioactive ion trap at RIKEN paves the way for future measurements of more exotic nuclei, and tests some of the key methods needed to build future rare-isotope accelerators.
Various models in nuclear physics can be used to fit the masses of known nuclei, but the predictions tend to be inconsistent for masses that have not been measured. A thorough study examines this problem and provides a route to quantify these errors.
The long-held belief that nuclear states of very heavy elements that carry a large angular momentum would be unstable has been shattered in recent years. Now, a new experiment that can probe the outermost nuclear orbitals in 250Fm studies these states and poses a challenge to theory.
