Thick Target Yield Measurements for Proton Induced Reactions with Mo, Co and Ni Elements in Havar Matrix for Proton Activation Analysis of Steel Alloys

The thick target yields for the nuclear reactions natNi(p,x)57Ni, natCo(p,x)58(m+g)Co and natMo(p,x)95g,96(m+g)Tc were measured, as a function of target thickness, using the thin foil activation technique with proton energy of 26.5 MeV. Haver material foils were used as a target, since it contains the natNi , natCo, and natMo with accurately certified concentrations. The measured yields, as a function of target thicknesses were, measured for proton activation analysis purposes. Haver alloy was used, as a reference for the analysis of some steel samples or iron based matrices, since it has almost the same stopping power for the accelerated protons. The produced gamma activities in the target due to these nuclear reactions were estimated for the same purposes. The measured yield values were compared to some previously estimated values, when it was possible
