Abstract
We measured integral thin target cross sections for the proton-induced production of He-, Ne-, and Ar-isotopes from Fe and Ni and of He-, Ne-, Ar-, Kr-, and Xe-isotopes from Bi from the respective reaction thresholds up to 2.6 GeV. Iron and Ni are important structural materials for the planned ADS/EA systems and Bi is a major constituent for planned spallation neutron sources. In addition, we give new data for the production of ³He from Mg, Al, Si, and Pb by revising earlier data and considering now ³H diffusive losses and new information for the ³H/³He branching ratios. The data are compared to results from theoretical nuclear model codes.
