Story summary

Researchers from the French National Centre for Scientific Research, led by Louis Lalanne, studied chromium-61, an isotope with 24 protons and 37 neutrons.
Their research focused on the 40-neutron island of inversion, where nucleons behave atypically.
New measurements indicate that chromium-61 defines the boundary of this inversion island, improving insights into nuclear structure evolution.
