| Abstract: | A study has been made of the concentration profiles of radioactive isotopes produced by transmutation in the YBa2Cu3O7−x
superconductor and PbZr0.54Ti0.46O3 ferroelectric by energetic protons (10 and 15 MeV), deuterons (4 MeV), and 3He and 4He nuclei (20 MeV). Profiles of two types have been observed: monotonic and with a maximum. It is shown that the type of isotope
concentration profile is determined by the nature of the cross-section energy dependence of the nuclear reaction producing
a given isotope.
