In a recent experiment at Argonne National Laboratory, new spectroscopic information was obtained for the mirror pair 67As and 67Se via the measurement of the lifetime of analogue 9/2+I excited states. The nuclei of interest were populated via the fusion evaporation reaction of 32S on 40Ca, and selected by the combination of Gammasphere, Microball and the Neutron Wall arrays. The mirror B(E1) strengths were measured via the centroid shift method in analogue E1 transitions in 67As and 67Se. These findings are significant in determining the extent of conservation of isospin symmetry.
