The main purpose of the paper is to give a generalization of the eigenfunction expansion and scattering theory developed by \textit{A. Ya. Povzner} [Mat. Sb., N. Ser. 32(74), 109--156 (1953; Zbl 0050.32201], \textit{L. D. Faddeev} [Uniqueness of solution of the inverse scattering problem. (Russian). Vestn. Leningr. Univ. 11, No. 7, Ser. Mat. Mekh. Astron. No. 2, 126--130 (1956)] and \textit{T. Ikebe} [Arch. Ration. Mech. Anal. 5, 1--34 (1960; Zbl 0145.36902)] for the selfadjoint Schrödinger operator in \(E_3\) to the non-selfadjoint case. The results are obtained in general under a typical limiting condition on the potential. The last sections contain a discussion of the time-dependent scattering theory and of the uniqueness of the solution for the scattering inverse problem.
