Compton scattering of photons causes image blurring since the secondary x-ray photon diverges from the primary beam. You are designing an x-ray detector system and wish to eliminate all photons that have scattered more than 25 degrees in an attempt to improve the resulting image quality. You are using monoenergetic x-ray source that emits photons with wavelength 8.9 x 10 to the power of -2 angstroms. Your detector is capable of discriminating the energy of the incoming photon by examining the pulse height. What range of photon energies will your system accept?
