This document presents the statistical description of neutron cross sections in the unresolved resonance range. The modeling of the total cross section and of the "shape - elastic" cross section is based on the "average R-Matrix" formalism. The partial cross sections describing the radiative capture, elastic scattering, inelastic scattering and fission process are calculated using the Hauser-Feshbach formalism with width fluctuation corrections. In the unresolved resonance range, these models depend on the average resonance parameters (neutron strenght function Sc, mean level spacing Dc, average partial reaction widths, channel radius ac, effectif radius R' and distant level parameter). The codes (NJOY, CALENDF...) dedicated to the processi...
