Excitation functions for the formation of 90Nb, 91mNb and 92mNb in the natZr(p,x) reactions
Abstract
The excitation function of the natZr(p,x)90Nb, natZr(p,x)91mNb and natZr(p,x)92mNb 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 natCu(p,x)62,65Zn 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 90Nb, 91mNb and 92mNb formation were also calculated.
