Abstract

Theβ-decay properties of neutron-rich Cu isotopes produced in proton-induced fission of 238U were studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. The data were collected using high-resolution online mass separation, reacceleration, and digital β-γ spectroscopy methods. An improved decay scheme of N=49 78Cu and the first observation of N=50 79Cu β-delayed neutron decay followed by a gamma transition are reported. Spin and parity (5^-) are deduced for 78gsCu. The β-delayed neutron branching ratios (P_βn) for the 77Cu and 79Cu precursors are analyzed with the help of nuclear structure models.
