Beam quality: Beam currents measured in a Faraday cup after the target were of the order of 200 nA. Target: The targets were made by vacuum evaporation of ZnO, enriched to 99.85% in 64Zn, on thin layer (~5 mu-g/cm2) of Au evaporated onto 15 mu-g/cm2 carbon backing. The 64Zn targets were typically ~10 mu-g/cm2. Data obtained: exported from EXFORThe electrostatic accelerator at the University of Sao Paulo. 5% errors for the cross sections was added to provide proper work of the NRV services.
