Nuclear structure studies of neutron-rich Cu and Zn isotopes produced by means of proton-induced fission of ²³⁸U

Summary, in English

The neutron-rich nuclei ⁷²Ni and ⁷²Cu have been produced in the proton-induced fission of ²³⁸U at the LISOL and ISOLDE facilities of Louvain-La-Neuve and CERN. Partial β-decay schemes are presented, giving some information about the nuclear structure of their daughter nuclei ⁷²Cu and ⁷²Zn. The lifetime of ⁷²Cu was determined to be T_1/2 = 6.63(3) s, in line with previous measurements. No β-decaying isomeric states were identified in ⁷²Cu, in contrast to ⁷⁰Cu. The spin and the parity of several states in ⁷²Cu are tentatively assigned and a comparison is made with different shell-model predictions.
