Nuclear Reactions of Silver and Indium with 200- and 400-MeV Protons

The cross sections of a number of ($p,ypxn$) reactions ($y=0-4,x=3-12\mathrm{}$) of silver and indium with 200- and 400-MeV protons have been determined. The results are compared with calculations based on the Vegas and Metropolis cascade codes and a Monte Carlo evaporation calculation. Poor agreement is obtained with respect to both the magnitude of the cross sections and the ratios of isobaric yields. Several possible sources of these discrepancies are discussed.
