Description
This work represents the results of an experimental investigation of the electromagnetic dissociation of 200 GeV/nucleon 16O and 32S ions in nuclear emulsions. Exclusive channels involving charged fragments have been studied as a function of the energy released and, assuming a Weizsaecker-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.
