II. New Data and Directions for Neutron Activation Analysis

In recent years substantial progress has been achieved in the field of Prompt Gamma-ray Activation Analysis (PGAA). The PGAA application also incorporates the use of short-lived activation analysis products. Recently, new precise k0 measurements for PGAA were performed at the Budapest Reactor. As part of an IAEA CRP, these data were combined with data from the Evaluated Nuclear Structure Data File (ENSDF) and the literature to create the Evaluated Gamma-ray Activation File (EGAF). Much of the data contained in EGAF pertains directly to the k0 values used in NAA, and there is an opportunity to evaluate the data from both communities to develop better databases for both applications. Additional data needs for Fast Neutron Activation Analysis (FNAA), will also be discussed.
