Summary: We study the three-body nonrelativistic quantum scattering problem with rapidly decreasing at infinity pair potentials for the case of one-dimensional particles. We consider the solution \(\chi(z,q)\) of the corresponding Schrödinger equation that can be interpreted as the scattered plane wave \(e^{i\langle z,q\rangle}\) and find its asymptotic behavior as \(|z|\to\infty\). More precisely, we explicitly construct a function \(\chi_0(z,q)\) that determines the asymptotic behavior of the solution up to a diverging circle wave with a smooth amplitude coefficient. The method is based on analogies between the quantum scattering problem and the diffraction of the plane wave by a system of half-transparent infinite screens. We believe that the formalism can be useful also for studying many-dimensional particle scattering and for the case of long range pair potentials.
