A publications with experimental cross-section
data were identified in the literature for incident particle energies up to 35
MeV and are represented with uncertainties in Fig. All
data. Three additional datasets containing each only one data point at
higher energy are not shown: Gambarini et al. (1969), Valentin et al. (1963),
and Vdovin et al. (1979). The results of 3 studies were rejected and not
considered for further analysis, and the reasons for their removal are
indicated: The remaining datasets were used as input for a least-squares Pade
fit. The Pade functions with 40 parameters were fitted to 607 selected data
points with a χ2=1.96 and covering the energy range up to 18
MeV as shown in Fig. Recommended. The uncertainties
(including 4% systematic uncertainty) range between 65% near the reaction
threshold, decrease to below 7% between 11 and 18 MeV and then monotonically increase
to10%.
