Pade approximation and the Monte Carlo method for data processing in neutron filtration experiments

The technique for data processing in neutron filtration experiments is described. The data processing includes insertion of corrections for the multiple scattering to the transmission functions and differential scattering cross sections, a search of the optimum cross section expansion by Legendre polymomials, obtaining subgroup parameters by means of the combined exponential analysis of the transmission function and its moments using the Pade approximation. Processing data for natural iron in the energy interval of neutron scattering (0.4-5.24) MeV are presented. The above technique makes possible the efficient solution of the problem of obtaining subgroup constants from the data on neutron filtration experiments
