A MONTE CARLO CALCULATION OF THE FERMI AGE AND OTHER PROPERTIES OF THE SLOWING DOWN DISTRIBUTION

摘要

A program was developed for the ORACLE which computes the second moment of the slowing down distribution of neutrons in a mixture of elements. The program allows mixtures of up to eight elements, four of which have scattering, absorption, and transport cross sections, and four which have only absorption cross sections. Provision is made to calculate other properties of the slowing down system, such as the average diffusion coefficient, the resonance escape probability, and the squared first and last flight mean free paths.
