Abstract
This work focus on the electromagnetic decay properties of the heaviest known mirror pair 67As and 67Se, produced in the fusion evaporation reaction 32S+40Ca, with a E=90MeV beam provided by the ATLAS accelerator at Argonne National Laboratory. The high selectivity required to investigate these proton-rich nuclei was achieved with the concurrent employment of Gammasphere, Neutron-Shell, and Microball. The full array allowed to obtain the level scheme of the 67Se nucleus up to 5.56 MeV, and 5 new transitions were assigned to the known 67As level-scheme. The level spin and parities were assigned using the ADO analysis and symmetry arguments. © 2009 American Institute of Physics.
