Photoneutron cross-section (PNCS) data are important in various current and emerging applications. Although a few sophisticated methods have been developed, there is still an urgent need to study the PNCS data. In this study, we propose the extraction of PNCS distributions using a combination of gamma activation and reaction yield ratio methods. To verify the validity of the proposed extraction method, experiments for generating
