Excitation functions of the reactions natEr(α,x)167,169Yb, natEr(α,x)172,173Tm, natYb(α,x)170,173,175,177m2Hf, natYb(α,x)171,172,177g,178mLu and natYb(α,x)169,177Yb were measured up to 38 MeV for application purposes (medical isotope production and charged particle activation analysis). The experimental excitation functions are compared to the theoretical calculations based on the model code ALICE-IPPE. The literature is very poor regarding cross section measurements on erbium or ytterbium irradiated with alpha particles. Yields of different production routes (proton-, deuteron- and alpha-irradiation) of 169Yb and 177Lu are compared.
