Isotope mapping capabilities using prompt gamma emission from epithermal neutrons

The time resolved Prompt Gamma Activation Analysis (T-PGAA) consists in the measurement of gamma energy spectrum induced by the radioactive capture as a function of incident neutron Time Of Flight. The PGAA spectrum in resonance or off-resonance conditions in the thermal-epithermal-fast ranges is presented to increase the elemental sensitivity and potential capabilities with respect to the NRCA and PGAA techniques. Moreover, the proposed method will introduce element specific sensitivity through incident neutron energy selection in PGAA spectra for multicomponent samples.
