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.
