Beam quality: The 14N beam was extracted from a Duoplasmatron ion source, and its intensity on the target was typically of the order of 50 nA. Target: The targets were prepared by evaporation of metallic cobalt, thickness of the order of 50 μg/cm2. Its were deposited on 5-10 μg/cm2 carbon backings. A thin layer of 2 μg/cm2 of 197Au was also deposited on the target for calculation and normalization purposes. Data obtained: exported from EXFORThe experiments were performed at the 8UD Pelletron accelerator of the University of Sao Paulo. The uncertainties in the differential cross section data vary from 1% to 10 % for the elastic scattering.
