Abstract: The β decay of 75Cu [t1/2 = 1.222(8) s] to levels in 75Zn was studied at the Holifield Radioactive Ion Beam
Facility of Oak Ridge National Laboratory. The γγ and βγ data were collected at the Low-energy Radioactive
Ion Beam Spectroscopy Station using the high-resolution isobar separator to obtain a purified 75Cu beam with
a rate of over 2000 ions per second. The excited states in 75Zn have been identified for the first time. A total of
120 γ-ray transitions were placed in a level scheme containing 59 levels including two states above the neutron
separation energy and a previously unknown 1/2− isomeric state at 127 keV. Spins and parities of several states
were deduced and interpreted based on the observed β feeding and γ-decay pattern.
