For this reaction a total of
nine works with experimental cross-section data were identified in the literature
for incident particle energies up to 100 MeV and are
represented with uncertainties in Fig. All data. The results of two
experimental sets were not considered for further analysis. The remaining seven
datasets were considered as input for a least-squares Pade fit. The Pade functions with
11 parameters were fitted to 125 selected data points with a χ2=1.43
and covering the energy range up to 100 MeV as shown
in Fig. Recommended. The uncertainties (including a 4% systematic uncertainty),
are 90% near the reaction threshold, decrease steadily to below 10% from 26 MeV to 80 MeV and increase
slightly for higher energies.
