摘要：

The measurement of the cross section for electron or photon-induced two-photon emission processes using a coincidence technique requires the determination of the efficiency-solid angle product for the two detectors. Since geometries for accelerator setups are usually quite complicated, the most accurate way to determine this product is by measuring a well-known two-photon process. A calibrated Ba-133 radioactive source is well suited for calibrating a coincidence system because it produces a high rate of coincident photons over a wide energy range from 31 to 384 keV. In this paper (K X-ray, gamma-ray) coincidence probabilities for Ba-133 decay are computed from the available nuclear and atomic data.
