New results on the natV(p,x)43Sc cross section: Analysis of the discrepancy with previous data

Abstract This work deals with the new cross section data obtained for the natV(p,x)43Sc nuclear reaction. We focus on this specific channel because we found a significant discrepancy with a recent NIM B publication, reporting extensive data on activation cross-sections induced by proton-Vanadium collisions up to 65 MeV. Proton-irradiation and γ -spectrometry were performed at ARRONAX facility (Nantes, France) by means of activation of stacked-foils targets up to 70 MeV. Our new experimental values are compared with all the previous measurements and supported by the results obtained with the reaction codes FLUKA, EMPIRE and TALYS. A discussion is given about the possible origin of the observed discrepancy.
