In the framework of the EURISOL DS project and within Task 11, we have performed in-target yield calculations for different configurations of thick direct targets. The production rates have been estimated using the MCNPX transport/generation code, coupled with the CINDER’90 evolution program. The yield distributions as a function of charge number Z and mass number A have been evaluated. Their production rates have been optimized for 11 selected elements and 23 of their isotopes of interest. Finally, the isotopic distributions for each of these 11 elements have been optimized in terms of the target material, its geometry, and incident proton energy.
