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

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

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 T1/2 = 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.
