CommentsBeam quality: The beam intensity was usually adjusted to 30-50 nA. Target: Target was about 100 mcg/cm2 thick. Data obtained: author graph (digitized with GSYS 2.4 ) The measurement were performed at the Laboratorio Nazionale del Sud in Catania using SMP Tandem Van de Graaff accelerator. The estimated error of absolute normalization is 7%. For the very forward angular region beam was reduced to the value 1 nA on 20 mcg/cm2 target.
