Statistical methods for the chemical compound identification from neutron-induced gamma-ray spectra

The paper presents a list correlation method to identify specific high explosive (HE) compounds from the spectra derived from reconstructed images of a gamma- ray camera. The correlation method uses all the information of the characteristic gamma rays for the associated elements of a compound. We show that the method is able to identify HE material at the compound level and the elemental level when spectra are line-broadened and in the presence of confounding clutter.
