O-16 (d,p)

Although the (d,p) reaction is a well established technique to analyze oxygen the corresponding cross sections were measured only in a limited energy range for several scattering angles. The most often the (d,p1)-reaction is employed for the analysis of thin oxide layers because the 16O(d,p1)17O cross section is much higher than the cross-section for the reaction with a residual nucleus remaining in a ground state. However the 16O(d,p0)17O reaction is also useful especially for thicker layers because protons from the 16O(d,p1)17O reaction may have insufficient energy to exit from the deep inside the oxide layer. In addition due to higher Q-value for the 16O(d,p0)17O reaction the p0 spectrum is located in a background free region whereas the p1 one may be obscured because of the interference from reaction products induced by deuterons interacting with different components in a sample. Only preliminary results are available at the moment for the evaluation of the cross-sections for 16O(d,p0)17O and 16O(d,p1)17O reactions.
