Cross Sections and Excitation Functions for the Production of Long-lived Radionuclides in Nuclear Reactions of Lead and Bismuth with Protons

Radiochemical separation procedures were developed allowing isolating the fractions of several long-lived radionuclides from lead and bismuth targets irradiated with protons in an energy interval from 0.1 GeV to 2.6 GeV. The cross sections of the isotopes 10Be, 26Al, 129I, 108mAg, 53Mn, 60Fe and 36Cl were determined and their excitation functions were calculated. The results are compared with theoretical predictions obtained by combination of INCL4 for the intra-nuclear cascade (first stage of the spallation reaction) and ABLA for the deexcitation phase (second stage).
