| Popis: | For the first time, cross sections of the 151Eu(α,xn)155−xTb (x = 2–6) reactions were measured by stack foil technique in the alpha particle range 60 → 19 MeV. Experimental excitation functions were compared with theoretical data from TENDL 2019 library and calculated by EMPIRE-3.2.3 code. Thick target yields for terbium radioisotopes were calculated. The possibility of the practical application of the studied reactions for the production of 152Tb and 149Tb was assessed. It was shown that higher energy of alpha particles is required to produce 149Tb. The production of 152Tb is affected by the influence of side reactions. It is possible to decrease the total content of impurities (153Tb+151Tb) at EOB to 18% of the activity of the 152Tb under 8-hour irradiation by limiting the energy range of incident particles to 42 → 34 MeV. The 152Tb yield will be 222 MBq/μA. |
