Fast fragments of the target in interactions of relativistic nuclei with nuclei of nuclear emulsion

Nuclear emulsions have been used to study the dependence of the characteristics of fast fragments on the masses and impact parameter of the interacting nuclei in the range of incident-particle masses from the proton up to neon. A substantial hardening of the energy spectra of the recoil nucleons from the target nucleus is observed with increase of the number of interacting nucleons in an individual event. A comprehensive comparison is made with the results of calculations according to the cascade-evaporative model.
