Theoretical nuclear physics

To test the validity of theoretical models, the predictions they make must be compared with experimental data. Instead of choosing one model out of many to describe mass measurements of zirconium, Bayesian statistics allows the averaging of a variety of models.

The tin isotope ¹⁰⁰Sn is key to understanding nuclear stability, but little is known about its properties. Precision measurements of closely related indium isotopes have now pinned down its mass.

Recent measurements of observables related to proton and neutron spin properties at low energies are in disagreement with the available theoretical predictions, and continue to challenge nuclear experimentalists and theorists alike.

A detailed analysis of a nucleon-knockout experiment has put forward a methodological roadmap for overcoming ambiguities in the interpretation of the data — promising access to the nuclear wave functions in unstable nuclei.

With increasing neutron number, the size of a nucleus grows, subject to subtle effects that act as fingerprints of its internal structure. A fresh look at potassium calls for theory to decipher the details.

The contact formalism describes short-range correlations, which play a crucial role in nuclear systems. Initially introduced for ultracold atoms, its generalization to the nuclear case was now validated by ab initio calculations.
