Excitation functions for the production of 60Fe and 53Mn in the reaction natPb(p,xp/yn)Z

The cross sections for the production of long-lived 60Fe and 53Mn from thin proton-irradiated lead foils in dependence on the proton energy from thresholds up to 2.6 GeV were determined by measuring the radionuclide content with accelerator mass spectrometry (AMS). For the sample preparations subsequent chemical separation procedures were developed. The corresponding excitation functions are shown. The results are compared with theoretical predictions obtained with calculation codes developed within the HINDAS project (5th framework of the EC). The knowledge of the radio nuclide inventory of such spallation targets is essential for the design of accelerator driven systems (ADS).
