New results challenge nuclear theory

The study is based on an experiment with radioactive beams at the ISOLDE facility at CERN, where researchers have succeeded in measuring the size of exotic potassium isotopes. In the international collaboration, the Chalmers researchers have contributed with the theoretical interpretation of the results.
“The study becomes really interesting when confronted with theoretical calculations. We find that previous claims that N = 32 would be a so-called magic number may not be so well-founded. We have also found that these new results challenge our understanding of the strong force between nucleons in very neutron-rich systems.” says Weiguang Jiang, postdoc at the Department of Physics at Chalmers.
