Correction of two particle eikonal scattering amplitude at large angles by means of a suitable dynamical impact representation is investigated. The representation is generated by the momentum transfer “averaged over the interaction”. Asymptotic expansion of dynamical momentum transfer in the inverse powers of energy is constructing by means of comparing the dynamical impact decomposition of full scattering ampliitude with ths ordinary one.
