The Photon Strength Function (PSF) Database contains all the experimental PSF data that were compiled by the IAEA Coordinated Research Project (CRP) on Generating a Reference Database for Photon Strength Functions. The methods that have been used to extract experimental PSF data are extensively described and assessed in the CRP technical report that is published in [1], and in the recent IAEA reports [2], [3], and [4]. The data files naming convention is self-explanatory and includes: the type and multipolarity of the PSF (1 stands for E1+M1), if it is data, , method used: , and the NSR keynumber is added for photonuclear data. For detailed definitions, please refer to our Glossary page. Each data file is accompanied by a with the same naming convention but with the extension `readme`. The README file contains all the information about the measurement, the experimental method, the model dependent analysis and parameters, as well as the reference.
