TL;DR: A study of the nobelium isotope 254No, with 102 protons and 152 neutrons, finds three excited structures, two of which are isomeric (metastable) and one of these structures is firmly assigned to a two-proton excitation, which provide a microscopic benchmark for nuclear models of the superheavy elements.
