Popis: For X-ray photon energies in the range E = 0.1 to 25 keV, a calculation of the mean energy to produce an electron-ion pair, w, in gaseous xenon, and the average number of primary electrons produced, N , is carried out, using a detailed Monte Carlo simulation. We found that the curve N (E) is a nonlinear function, with sharp steps close to the xenon absorption edges. Moreover, w was found to be energy dependent, with values ranging from 21.7 to 24.6 eV. An interpretation of the calculated result is made in terms of the contribution of the different subshells for photoelectron and Auger/Coster-Kronig electron production.
