Neutron resonance transmission (NRT) and prompt gamma activation analysis (PGAA) are nuclear techniques for isotope analysis based on the measurement of the transmitted neutron beam and neutron capture gamma ray spectrum. In this work, we propose to combine these neutron techniques to enhance element sensitivity and localize hidden inclusions inside samples. Neutron capture gamma ray self-absorption, solid angle information, and neutron resonance transmission will be used to this aim. In addition, the gamma ray background of the irradiation beamline will be studied.
