The method of impulse approximation is used to check the validity of the first-order optical potential for the elastic scattering problem of the neutron on the bound system, namely, [Formula: see text] and [Formula: see text]at incident neutron energies of 155 and 225[Formula: see text]MeV. The optical potential is derived as the first-order term within the spectator expansion of a nonrelativistic multiple scattering terms using the Lippmann–Schwinger equation. The Modern realistic two-body potential ArgonneV18 in the momentum space was used as input in the Lippmann–Schwinger equation. The obtained results for the elastic differential cross-sections are in a good agreement with the experimental data taken from EXFOR Database for all studied targets at neutron energy above 200[Formula: see text]MeV. As the neutron energy decreases down to approximately 155[Formula: see text]MeV, the discrepancies with experimental data appear, which is in accordance with the impulse approximation formalism.
