Abstract:
We report on the first use of post-accelerated radioactive isomeric beams. Long-lived isomeric states in 68 Cu and 70 Cu have been produced and separated at ISOLDE, CERN. Subsequently they were post-accelerated to 2.86 MeV/u and sent to a target in the center of the MINIBALL spectrometer, used for the detection of the γ-rays of interest. The preliminary results from the Coulomb excitation of the I π =6 - , 1 + states in 68 Cu and the I π =6 - one in 70 Cu , compared to a large-scale shell model calculations, hint the importance of the excitations across the Z=28 gap for the understanding of the nuclear structure in the neutron-rich N=40 region.
