This work presents the determination of the Gd-148 and Dy-154 content in Pb targets irradiated by 220-2600 MeV protons. It includes the chemical separation of lanthanides, followed by the preparation of proper samples, by molecular plating technique, for alpha-spectrometry measurements. The experimental cross section results were compared with theoretical predictions, calculated with the INCL++-ABLA07 code. The comparisons showed a satisfactory agreement for Gd-148 (less than within a factor two), while measured Dy-154 cross sections are higher than the theoretical values.
