Parametrization of cross sections for neutron interaction with $^{1}$H, $^{2}$H and $^{12}$C nuclei at energies between 20 and 90 MeV

Abstract

The experimental data for neutron interaction with $^{1}$H, $^{2}$H and $^{12}$C nuclei are parametrized in energy range 20 to 90 MeV. The energy dependence of the total and reaction cross section is represented in the form of a series of orthogonal polynomials. The logarithm of differential cross section for the angular distribution is expressed as a linear combination of Legendre polynomials with the energy dependence of their coefficients described by a series of orthogonal polynomials
