NUCLEAR-REACTIONS OF SILVER WITH 25.2 GEV C-12 IONS AND 300 GEV PROTONS

Cross sections for the production of approximately 100 radionuclides in the interaction of silver with 25.2 GeV C12 ions and 300 GeV protons have been determined. The results have been parametrized in terms of a 10-parameter equation which accurately reproduces the measured isobaric- and mass-yield curves. The cross sections of products in the A=40-106 mass range are consistent with the factorization hypothesis. At lower mass numbers, the yields of products formed in reactions induced by C12 ions are enhanced by over a factor-of-2 relative to the ratio of total reaction cross sections. The results are compared with Monte Carlo cascade-evaporation calculations and with the abrasion-ablation model. NUCLEAR REACTIONS Ag(C12, spallation) and Ag(p, spallation) EC12=25.2 GeV, EP=300 GeV.
