Isotopic effects of fragment-yields in proton induced reactions on Sn isotopes Original Research Article

Analysis of isotopic characteristics of products related to the inclusive data measured using activation method in proton reactions at the energies 0.66, 1.0 and 8.1 GeV with separated tin isotopes is presented. Experimental results are systematized in form of cross section ratios for two targets of different isotope composition. Scaling behavior is observed for reactions with heavy residuals in the same manner as in light fragment production processes. These results are discussed in the light of relevant recent data. Finally, dependence of scaling parameters on the target neutron excess is observed.
