Asymptotic behavior of the scattering amplitude for two scalar particles at high energy and fixed momentum transfers is reconsidered in quantum field theory. In the framework of the quasi-potential approach and using the modified perturbation theory the leading eikonal scattering amplitude and its corrections are constructed. Also, the differential cross section is discussed. Several interaction potentials, Yukawa, Gauss and Newton are used to illustrate the problem.
