Excitation functions for the production of 155Tb, 156(ml+m2+g)Tb, 160Tb and 161Tb by (alpha,3pxn) reactions on natural dysprosium were experimentally determined by the method of activation of stacked metallic foils. The irradiations were performed in the external beam of the isochronous cyclotron at Karlsmhe (Germany) with co-particles up to 88.5 MeV. Gamma-rays spectrometry with an n-type intrinsic coaxial Ge detector was used to detemine the reaction product activities. The data are compared with theoretieal predictions provided by equilibrium and pre-equilibrium reaction models. Thick target yields for the production of 155Tb, 156(ml+m2)+g)Th, 160Tb and 16"lTb are presented.
