Cross-section measurements of the natZr(α,x)93m/99Mo reactions up to 30 MeV

The nuclear reaction cross-sections of the nat Zr(α,x) 93m/99 Mo reactions were measured up to 30 MeV in six irradiation experiments using the stacked-foil technique. Irradiations were carried out at the level IV cyclotron IBA Cyclone 30 XP at INM-5, Forschungszentrum Jülich. The nat Cu(α,x) 66/67 Ga reactions served as monitor reactions to determine the α-particle flux and energy. The experimental data and the derived integral yield curves were compared with literature values, TENDL-2025 data and TALYS-2.0 calculations.
