Correction of the counting losses in a photon spectrum owing to gamma-gamma, gamma-X and X-X coincidence summing
Description
Coincidence summing between gamma and X-rays disturbs photon spectra. So, a program making the corrections of the counting losses owing to this effect was realized. Any decay scheme (β-, β+ electron capture) can be treated. First developed for pin-point sources, the calculation was extended to disc shaped and cylindrical sources, by computing the efficiency for any point from a reference position

Les spectres de photons sont perturbes de facon plus ou moins importante par des phenomenes de coincidences entre les raies gamma et X. Un programme permettant d'effectuer les corrections des pertes de comptage dues a ces effets a donc ete mis au point. Il s'adapte a l'ensemble des schemas de desintegration (β-, β+, capture electronique). Le calcul, developpe pour des sources ponctuelles a ete etendu au cas de sources discales et cylindriques en evaluant l'efficacite en chaque point a partir d'une position de referenceFiles
