Experimental study of α-particle induced reactions on natural erbium for the production of Auger-emitters 167Tm, 165Er and 169Yb

The cross sections for nuclear reactions natEr(α,x) were measured in the energy range 60 → 10 MeV using the stacked-foil technique. The experiments were carried out in a wider energy range in comparison with previous works. The results are consistent with other studies and modeling using TENDL-2019....

Description
Summary:The cross sections for nuclear reactions natEr(α,x) were measured in the energy range 60 → 10 MeV using the stacked-foil technique. The experiments were carried out in a wider energy range in comparison with previous works. The results are consistent with other studies and modeling using TENDL-2019. The 167Tm yield was 5.4 MBq/μAh in the range 60 → 30 MeV, and the main long-lived impurity is 168Tm (0.78% in terms of activity). The 165Tm yield is 4.6 MBq/μAh (60 → 40 MeV). 169Yb is formed with a yield of 1.0 MBq/μAh in the energy range 60 → 20 MeV. •Activation cross-sections of alpha-particle induced reactions were measured on natural erbium target.•Stacked-foil technique, activation method and gamma-spectroscopy were used.•Cross section for ytterbium (167,169Yb and thulium (165Tm, 166Tm, 167cumTm, 168Tm) were determined.•Production routs of 169Yb, 167Tm and 165Er were discussed.
