The yield of transtarget produced in the reaction of 47 MeV/u 12 C bombardment on cesium compound targets are measured by means of nuclear chemical method and the off line γ spectrum technique. The measurement results show that reaction cross sections of transtarget products are considerable. The isotope distribution peak position (mass number) of barium element is 129.7±0.2 and the distribution width parameter is 2.76±0.25. At the same time, the yields of products with up to five charge numbers larger than target nucleus have been obtained.
