Abstract: Analytical expressions for calculation of yield of scattered neutrons from the two-component sample СН2 at the angles of 15, 20, 25 and 30° were received. The analysis of the range of validity of the obtained expressions depending on the structure of investigated cross sections was carried out.

Keywords: two-component sample (scatterer), scattered neutrons, transmission method, code MCNP4с.
