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

摘要

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 ~(10)Be, ~(26)Al, ~(129)I, ~(108m)Ag, ~(53)Mn, ~(60)Fe and ~(36)Cl were determined and their excitation functions were calculated. The results are compaxed 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).
