The correspondence between the asymptotic behavior of the amplitude with respect to momentum transfer in the lower approximations of perturbation theory and the position of the Regge poles is established for the case of scattering by a Yukawa potential. The consistency of perturbation theory with the presence of only moving poles can be verified in the higher approximations. The method developed is applied for investigation of relativistic field theory. It is found that the simple picture analogous to potential scattering does not agree with this result in perturbation theory. As a possible solution of the problem it is suggested that poles accumulate near integral negative points (and possibly near zero) because of the existence of many channels in field theory. (auth)
