Badikov, E. Gai, N. Rabotnov] The problems due primarily to the limitations of modern computers, preventing adoption of modern methods for estimating neutron data in everyday practice and making it difficult to use the estimated data in applied programs, are discussed. Possible solutions of these problems are presented. Specifically, an identity transformation of the statistical functional to be minimized is found: this transformation makes it possible to avoid the construction, storage, and numerical inversion of superlarge covariation matrices of measurement uncertainties. The transformation makes it possible to perform statistical analysis of an arbitrarily large number of measurements. An efficient method of parameterization of the cross sections of neutron reactions at high neutron energy is proposed. The method is based on the use of the Adler-Adler resonance formula for fitting the cross sections. The parameters in the formula in this case do not have a clear physical interpretation. The method makes it possible to decrease substantially the volume of information to be stored in estimated data files in ENDF-6 format. For three cross sections (total, fission, and radiative capture), the proposed parameterization is universal, and it makes it possible to represent the cross section in a single manner from the thermal point up to an arbitrarily high neutron energy. The results of this work are illustrated for estimation of the cross section of the reaction241Am (n,f). 1 figure, 1 table, 27 references.
