Deep inelastic nuclear reactions

Deep inelastic nuclear reactions under hadron effect are discussed. The problem of separating contributions of quasifree and deep inelastic processes to the cross section is considered. The strong A-dependence of cross-sections of cumulative particle production in deep inelastic reactions is noted. When studying A-dependence the isotopic effect was revealed: proton (neutron) yields of heavy nucleus isotopes don't change if the neutron (proton) number in target nucleus changes. It is concluded that deep inelastic nuclear reactions represent the result of incident particle interaction with several nucleons in intimate group inside the nucleus. Nucleons in this group combine into one quark bag
