ABOUT TARGET FRAGMENTATION IN NUCLEAR EMULSION AT RELATIVISTIC ENERGY

The interaction of proton with nuclear emulsion at 3.7 GeV reveals the picture of hadronnucleus collision. The nucleusnucleus collisions are given in the interactions of 4He and 7Li with emulsion nuclei at nearly the same energy (2A GeV).On the other hand, the relativistic energy (a few GeV/nucleon) is a special energy, at which the nuclear limiting fragmentation applies initially. Therefore, the target fragmentation is studied by selecting samples of inelastic interaction events having no emission of relativistic hadrons. The multiplicity characteristics of the produced target fragments are studied. The dependence of the target fragments on the projectile size has been analyzed. The complete destruction of Ag target nuclei has been observed innucleus nucleus interactions at number of heavily ionizing particles (Nh) 28.
