Eight publications with
experimental cross-section data were identified in the literature for incident
particle energies up to 20 MeV and are represented with uncertainties in Fig. All data. The original publication of Barnett et
al. (1968) contains a large number of relative measurements using β+
counting (marked as (a)) and 3 absolute measurements around 5.5 MeV (b). The
data set Barnett (a) was normalised to these 3 data points. All values were
divided by two (photon multiplicity from positron annihilation) for use in the
evaluation. The results of 3 studies were rejected, 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 93 parameters were fitted to
389 selected data points with a χ2=2.40 and covering the energy
range up to 20 MeV as shown in Fig. Recommended. The
uncertainties (including a 4% systematic uncertainty) are very high (60%) near
the reaction threshold, reach 5.5% around 6 MeV and remain at that figure over
the whole studied energy range.
