Bibliography of experimental data
Although 124I gains importance as a therapeutic isotope, in the production route of 123I on 124Te targets it represents a disturbing nuclidic impurity.
A total of 8 cross section data sets (from 6 papers) were found in the literature in the energy region considered. From these 6 sets were excluded while the 2 remaining sets were selected for further evaluation. The list of related references given below is accompanied with additional information. We mention availability of data in the computerized 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 *).

The data from papers where experimental numerical values were available (8 data sets from 7 papers), are collected in All data. From these 6 works were excluded while the remaining 2 works were selected for further evaluation.
Cross sections were calculated by the nuclear reaction model code ALICE IPPE. The results are compared to selected experimental data in Selected. The result of model calculation after normalization excellently reproduces the experimental data. The IPPE calculation (normalized to Scholten (95) and Acerbi (75b) maximum cross section values) was chosen as recommended data. Recommended cross sections are compared with selected experimental data, including their error bars, in Recommended. Yields calculated from the recommended cross sections are presented in Yield. The corresponding numerical values for recommended cross sections and yields are tabulated in Tabulated Cs and Tabulated Y, respectively.
