Validation and upgrading of the recommended cross section data of charged particle reactions used for production of PET radioisotopes

摘要

A validation test and upgrading of the recommended cross section database for production of PET radioisotopes in charged particle induced reactions, published by the IAEA in 2001, was performed. Experimental microscopic cross section data published earlier or measured recently and not yet included in the evaluation work of IAEA were collected and added to the primary database in order to improve the quality of the recommended data. The newly compiled experimental data supported the previous recommended data in most cases, but in a few cases this influenced the decision made earlier and resulted in new selected cross section data sets. A spline fitting method was applied to the selected data sets and updated recommended data were produced in these cases. The integral thick target yields deduced from the new recommended cross sections were critically compared with experimental yield data available in the literature.
