Abstract

Cross sections for charge-exchange reactions induced by the interaction between 12C ions of energy E12C = 2.2 GeV per nucleon and tin targets enriched in the isotopes 118,120,124Sn were measured by the induced-activity method. The cross sections for products whose charge numbers were in excess of the target charge number (Sb and Te) were determined. The shape of the isotope distribution of Sb products was indicative of the evaporative character of neutron emission in the formation of final-state products. The dependence of cross sections for charge-exchange reactions on the nucleonic composition of the target was considered. The contribution of electromagnetic excitation to the cross section for the reaction 124Sn(12C, x)124Sn was estimated.
