Fragmentation of Nuclei under the Effect of Radiation of Various Types

An analytic approximation is proposed for a determination of the distribution of the inelastic energy loss of charged fragments originating from nuclear reactions induced by collisions of protons, photons, and electrons with silicon nuclei. It is shown that, in the energy range between 3 and 10 GeV, the effect of the hadronization process on this distribution for heavy secondary ions increases with incident-radiation energy. A strong asymmetry of the distribution calculated for collisions with relativistic electrons is indicative of a momentum transfer to only a small fragment of the nucleus involved.
