Production cross sections of dysprosium, terbium and gadolinium radioisotopes from the alpha-particle-induced reactions on natural gadolinium up to 50 MeV.

The activation cross sections of the alpha-particle-induced reactions on natural gadolinium up to 50 MeV were measured. The stacked foil technique, the activation method and the γ-ray spectrometry were used for the measurement. We determined the experimental production cross sections of 155,157,159Dy, 153,155,156g,160,161Tb and 153Gd. No previous experimental data of 155,159Dy, and 153Gd were found in the literature. The measured values were compared with the previous experimental data and the TENDL-2019 data. [ABSTRACT FROM AUTHOR]
