Isotope effect in yields of nuclear reactions

Abstract

The analysis results of the isotopic yields for products obtained in reactions of protons at energies 0.66, 1, 8.1GeV with separated tin isotopes are presented. The experimental data are compared in form of reactions of element cross sections for two targets of different isotope compositions. The scaling behaviour have been shown in the dependence of this ratios from neutron and proton composition at the reaction products. The discussion of scaling parameters allows to explain the mechanism of light and medium mass fragment production.
