Evolution of Nuclear Structure: From Semi-Magicity to Magicity in the Neutron-Rich Copper Isotopes

Evolution de la structure nucléaire : De semi-magicité à magicité dans les isotopes de cuivre riches en neutrons

Résumé

The neutron-rich copper isotopes have generated substantial interest over the last decades, thanks to the simple picture they present of a single proton outside the closed Z = 28 nickel core. At the semi-magic neutron number N = 40, the single-particle nature of the lowest excited states affirms itself through distinct and sudden structural changes. It remains firmly apparent along the isotopic chain, which is illustrated by thetransparent interpretation of weakly coupled valence particles that holds for the odd-odd isotopes. The availability of competing configurations, however, never stays far away, and provides fertile ground for the appearance of shape coexistence at the N = 50 magic number. In this contribution we intend to bring together the extensive experimental input from various probes involving transfer reactions, in-flight, decay as well as laser spectroscopy over the last twenty years, and offer an overview of the theoretical endeavour by which it has been accompanied.
