Activation cross sections for reactions of 109Ag induced with 40Ar ions

Activation cross sections for reactions of enriched targets of 109Ag with 40Ar ions of 288 and 228 MeV have been determined by γ-ray spectroscopy. Yields of evaporation residues and low-mass transfer products have been measured. Evaporation residue yield-mass distributions are compared with three sets of statistical model results. The calculation based on a rotating liquid drop model with fission competition is in very good agreement with experimental results. It is shown that the yields are inconsistent with a mechanism of incomplete fusion plus evaporation. (Auth.)
