Isoeffect in reactions on enriched tin isotopes with 12C ions at 2.2AGeV energy

The analysis of isotope effect in experimental data from reactions on enriched tin isotopes with 12C-ions at energy 26.4 GeV is presented and compared with previous data obtained in protons, deuterons induced reactions on the same targets.Dependence of the target isospin is observed for different mass reaction products. The parameterization of cross-section ratios in frames of known empiric relations is made. The obtained parameter B behavior is discussed in the range of light and heavy products and for targets with different isotope composition.
