We have measured the formation cross sections and the recoil properties of the products from the interaction of 240 MeV 12C with natural Ag targets. From the data, we have constructed charge- and mass-distribution curves. With the measured recoil range and forward-to-backward ratios, we deduced the formation mechanisms, and found that the yields in the mass range between A = 40 and A = 70, with a total cross section of 6 ± 1 mb, were mainly formed by the fission process. The yields between A = 70 and A = 130, with a total cross section of 2300 ± 200 mb, were formed by direct reactions in which the target-like transfer reaction products contributed 1000 ± 100 mb and spallation reactions contributed 1306 ± 200 mb.

This work represents the results of an experimental investigation of the electromagnetic dissociation of 200 GeV/nucleon 16 O and 32 S ions in nuclear emulsions. Exclusive channels involving charged fragments have been studied as a function of the energy released, and, assuming a Weizsäcker-Williams spectrum of virtual photons, there is a good agreement with results for the (γ, p) processes obtained with real photons. However, the rates found for other processes are larger, in particular for the (γ, α) on both nuclei. The values of the total integrated absorption cross sections are generally larger than those obtained from real photon experiments but the extent of the discrepancy depends strongly upon which photon results are used in the comparison.
