The β decay studies of ^75Cu using LeRIBSS

The β decay of ^75Cu (t_1/2=1.222(8),s) to levels in ^75Zn has been studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. The γγ and βγ data were collected using the Low-energy Radioactive Ion Beam Spectroscopy Station making use of the high-resolution isobar separator. This resulted in considerable information on the previously unknown level structure of ^75Zn with some 120 γ-ray transitions placed in a level scheme containing 59 levels including two states above the neutron separation energy. A previously unknown 1/2^- isomeric state at 127 keV is proposed. In addition, spins and parities of several states are proposed based on the observed decay pattern. These states can be explained in terms of coupling neutrons in the 1g_9/2 and 2p_1/2 orbitals to protons in the 1g_5/2 and 2p_3/2 orbitals. Results of β decay studies of ^75Cu will be presented.
