The increasing importance of Prompt Gamma Activation Analysis (PGAA) and its broad range of applicability have been emphasized at many meetings related to this topic. Inaccuracy and incompleteness of the data available for use in PGAA are a significant hindrance in the qualitative and quantitative analysis of complicated capture-gamma-ray spectra. A Coordinated Research Progamme on the subject organized by the International Atomic Energy Agency has as its goal to create a new evaluated database that includes a combination of nuclear physics data from the Evaluated Nuclear Structure Data File, physical theory, and recent systematic measurements. Laboratories from China, Hungary, India, Korea, Vietnam, and the United States of America are participating in this project. Main results from these laboratories are presented in this paper.
