Calculated response of intrinsic germanium detectors to narrow beams of photons with energies up to ∼300 keV

The response of small intrinsic Ge detectors has been calculated for photons incident with energies up to ∼300 keV. The results include the effects of scattering and escape from the detector of the photons and of Ge characteristic X-rays produced in photoelectric absorption. Included also are the effects of the backscattering of photons from material behind the detector. The results, based on Monte Carlo calculations for various photon energies...
