Accounting p-wave resonance effect in analysis of experimental neutron transmission through iron samples

Analysis of experimental data on neutron transmission through iron samples with account of s- and p-waves effect in different energy groups is carried out on the basis of the theoretical model previously developed for description of energy averaged transmission of resonance neutrons as functions of sample thickness and average resonance parameters. As a result, one can find more accurate values of minimal sections in comparison with the analysis, accounting only s-wave effect, and also values of p-wave resonance parameters in groups, being in agreement with corresponding evaluated values. With the help of evaluated nuclear data it is possible to present data of resonance averaged transmission of neutrons through sample of arbitrary thickness
