Bibliography of experimental data
Four data sets with experimental cross section data were identified in the literature in the considered energy range but only the independent data are represented with uncertainties in Fig. All data. Data published by Hermanne et al (2002) in Nucl. Instrum. Meth. Phys. Res. B 187 (2002) 3–14 are identical with the data published in J. Nucl. Sci. Technol. Suppl. 2 (2002) 1286–1289. Data points below the threshold energy reported by Ditroi et al. (2011) were deleted. Three independent data sets were used as input for a least-square Pade fit. The Pade functions with 9 parameters were fitted to 49 selected data points with a χ2=0.87 and covering the energy range up to 50 MeV as shown in Fig. Recommended. The uncertainty (including a 4% systematic uncertainty) ranges from 86% near the reaction threshold and decrease to 6% around 15 MeV and stays at 6% till 50 MeV energy.
