Description

One of the challenges nowadays in nuclear physics is to study nuclei as far as possible from stability. In these so-called exotic regions, the nuclear structure is strongly evolving. As a consequence, the “classical” magic numbers (8, 20, 28, 50, 82, 126) are not universal over the nuclear chart and unexpected behaviors may appear for extreme N/Z ratio. This presentation focuses on the exotic region of ${}^{78}$Ni, presumed to be doubly magic ($Z=28$, $N=50$), and more specifically on the $Z=28$ shell gap to see whether it weakens when adding neutrons beyond $N=40$. This is done through the study of copper isotopes (core of nickel + 1 proton). We focus here on neutron-rich ${}^{79}$Cu, produced through proton knock-out at RIKEN in Japan.
