CommentsBeam quality: 13N2+ beams are postaccelerated to energies of 16.3, 20.0, and 29.5 MeV, with intensities up to about 1.2 108 particles/s Target: The 12C and 13C self-supporting targets, 40 μg/cm thick, were produced by evaporation in Louvainla- Data obtained: author graph (digitized with GSYS 2.4 ) The experiments were performed at the Louvain-la-Neuve facility. The 13N radioactive beam of Louvain-la-Neuve is obtained by a two-cyclotron scheme.
