The quantum graph model of junction of zig-zag and armchair signle-wall carbon nanotubes is considered. The spectrum is completely described. A condition on appearance of states localized near the interface is provided. All localized states are explicitly calculated.
Keywords: carbone nanotube, quantum graph, scattering.
