Nature Physics: Charge radii of exotic potassium isotopes challenge nuclear structure theory

“In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in both experimental and theoretical nuclear physics from University of Jyväskylä, Finland, took part of international research team, which studied the nuclear charge radii of potassium isotopes. Isotopes were studied by using the collinear resonance ionization spectroscopy technique. The results indicated that the potassium isotope with a neutron number of 32 does not conform with criteria of magic neutron number. The results were published in Nature Physics journal on January 2021.”
