摘要

Cross sections for charge-exchange reactions induced by the interaction between ~(12)C ions of energy E _(12C) = 2.2 GeV per nucleon and tin targets enriched in the isotopes ~(118,120,124)Sn 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 ~(124)Sn(~(12)C, x) ~(124)Sn was estimated.
