The Study and Analysis of Neutron Activation with the Application of Gamma Ray Emission

. In the neutron activation method, gamma ray is used to trigger and activate neutron. In this method, isotropic neutron sources, its generators, and thermal triggers are studied and analyzed. In this paper, a number of computational and analytical methods, including Monte-Carlo simulation method and Maxwell-Boltzmann method, have been used to enable us to perform large-sample prompt gamma neutron-activation analysis (LS-PGNAA) and to use this large-sample in simulation and laboratory samples.
