Abstract

Cross sections of α-induced reactions on natural zirconium were measured up to 50 MeV using the stacked-foil technique, activation method and high resolution γ-ray spectrometry. The production cross sections of ^93m,99Mo, ^{90g,92m,95g,95m,96}Nb and ^88,89g,95Zr were determined and compared with other experimental data measured earlier and result of theoretical calculations. The integral thick target yield of ⁹⁹Mo was deduced from the measured cross section data.
