  "abstract": "In a quasi-one-dimensional system (a tube) with low concentration of defects $n$ the resistivity $\\rho$ has peaks (van-Hove singularities) as a function of Fermi-energy. We show that due to non-Born scattering effects a deep narrow gap should appear just in the center of each peak. The resistivity at the bottom of a gap ($\\rho_{\\min}\\propto n^2$) is dominated by scattering at rare \"twin\" pairs of close defects, while scattering at solitary defects is suppressed. The predicted effect is characteristic for multi-channel systems, it can not be observed in strictly one-dimensional one.",
