Abstract

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, 99 Mo, 90g, 92m, 95g, 95m, 96 Nb and 88, 89g, 95 Zr were determined and compared with other experimental data measured earlier and result of theoretical calculations. The integral thick target yield of 99 Mo was deduced from the measured cross section data. Highlights: Excitation functions of α-induced reaction on nat Zr up to 50 MeV were measured. Production cross sections of Mo, Nb and Zr radioisotopes were determined. End of bombardment activity of 99 Mo was deduced.
