There were 6 experimental published papers dealing with the measurement of the activation product ¹⁸F. From the papers considered here 3 works were excluded and the remaining 3 were selected for further evaluation. The list of related references given below is accompanied with additional information. We mention availability of data in the computerised database EXFOR (if available, unique EXFOR reference number is given). Further, we indicate a reason why a data set was excluded (reference denoted by an asterisk *).

It should be pointed out that at low energies the ²⁰Ne(d,a)¹⁸F reaction is the only contributing process to the formation of ¹⁸F. Above 30 MeV the ²⁰Ne(d,2p2n)¹⁸F reaction also contributes. The contributions from reactions induced on ²¹Ne and ²²Ne are expected to be significant only at high energies.

The data from papers where experimental numerical values were available (6 papers), are collected in Fig. 5.2.6a. From these 3 works were excluded while the remaining 3 were selected for further evaluation.

Cross sections were calculated by the nuclear reaction model code SPEC and by two fitting procedures (Padé with 9 parameters and Spline). These results are compared with the calculation selected experimental data in Fig. 5.2.6b. It is seen that the SPEC underpredicts the data below 8 MeV as well as above 13 MeV. The best approximation was judged to be the spline fit. The recommended cross section curve is compared with selected experimental data, including their error bars, in Fig. 5.2.6c. Te yields calculated from the recommended cross sections are presented in Fig. 5.2.6d. The corresponding numerical values for recommended cross sections and yields are tabulated in Tab. 5.2.6a and Tab. 5.2.6b, respectively.
