Proton-induced polonium production in massive lead–bismuth target irradiated by 660 MeV protons

Abstract The paper presents study of polonium production in bismuth foils placed in lead target. Proton-induced production of residual nuclei 206 Po, 207 Po, 208 Po, 209 Po, 210 Po in 209 Bi foils placed in lead target irradiated by 660 MeV protons was calculated. A comparison with calculated spatial distribution of polonium production using an MCNPX code and experimental results has been performed. The results of calculation will be useful for design of target of Subcritical Assembly in Dubna (SAD).
