Abstrakt: The excitation function of the nat Zr(p,x) 90 Nb, nat Zr(p,x) 91 m Nb and nat Zr(p,x) 92 m Nb reactions were measured within the incident proton energies range of 10.58 MeV to 43.61 MeV, based on the stacked-foil activation technique. The degradation of proton energy along the sample stack was calculated using the code SRIM-2013, and the proton flux was determined by using the nat Cu(p,x) 62 , 65 Zn monitor reactions. The induced γ -ray activity needed to determine the reaction cross-section was measured by using an HPGe detector. The measured cross sections are compared with the literature data and with the theoretical predictions based on TALYS-1.95 code. For the theoretical calculations, the effect of different level density models and γ -ray strength functions was taken into account. Besides the measured excitation functions, the integral yields of 90 Nb, 91 m Nb and 92 m Nb formation were also calculated. [ABSTRACT FROM AUTHOR]
