Physics –Radiation Interaction with MatterPhysics –Radiation Interaction with Matter
Gamma Resonance Technology, GRTGamma Resonance Technology, GRTis based on resonance interaction of gamma radiation with a specific level in a nucleus of an element of interest, e.g., N, O, Cl, and detection of the transmitted incident radiation or that induced by nuclear fluorescence.
Photo-Fission Technology, PFTPhoto-Fission Technology, PFT is based on nuclear absorption of energetic gamma rays that above threshold energy induce fission in fissile materials, e.g., U-235, Pu-239, Th-232, and subsequent detection of the emitted delayed neutrons.
High-Z Detection Technology, HZTHigh-Z Detection Technology, HZTis based on attenuation of dual or triple high energy gamma beams and solving simultaneous transmission equations for resolving high- and low-z materials.

A low energy proton beamhits a dedicated target andproduces resonance gammarays. These interact resonantly with N or Cl encountered in the explosive.
Monitoring the transmittedand the scattered beams,with the transmission and scattering detectors,respectively, allows analysisand imaging of the elements of interest.

• Resonant gamma-rays are emitted at α =80.66o to the beam, where DE(Doppler) = 2 x nuclear-recoil•The 9.17 MeV emission line is broadened to ~520eV
Contributions to line broadening are:• Nuclear level width – 128 eV• Proton beam resolution – few-eV per keV beam spread• Proton beam optics – typically ~100 eV• Doppler vibrations of target nuclei – 40-80 eV• Atomic excitations concomitant with (p, ) – 480 eV
