Cu decay into neutron-rich Zn isotopes: shell structure near 78Ni - β-decay study of 75Cu

Abstract

Doubly-magic nuclei are the cornerstone of our current understanding of the nuclear shell model. These nuclei have spherical shapes and are more tightly bound than any other in the nuclear chart. Just recently, this selected club has accepted its newest member, the very exotic 78Ni. The neighbouring nuclei around doubly-magic ones are expected to show similar, however weaker, characteristics. For this reason, an experiment was conducted at ISOLDE Decay station (IDS) to study the decay of neutron-rich Cu isotopes into Zn isotopes just above the two double magic 68Ni and 78Ni. In this work part of the collected data were analyzed and, in particular, the level scheme of 75Zn was expanded
