Abstract
Excitation functions of the reactions ^natEr(α,x)^167,169Yb, ^natEr(α,x)^172,173Tm, ^natYb(α,x)^{170,173,175,177m2}Hf, ^natYb(α,x)^{171,172,177g,178m}Lu 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.
