Nuclear Physics

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.

Nuclear Physics

When an antiproton is fired into an atomic nucleus, will it live long enough for the nucleus to respond to the attractive strong force between the antiproton and the protons and neutrons? Calculations suggest that it would and predict the experimental signatures of an antiproton annihilating in a locally compressed nucleus.
