英文摘要	We develop a general multiple-scattering partial-wave theory for topological insulator (ti) surfaces and derive cross sections (css) for single-and two-centered scattering. we show that on gapped ti surfaces the symmetry of the differential cs is reduced, and that backscattering occurs. a sharp resonance peak in the total cs a(tot) of heights 30-55 nm is found at the band edge similar to 50 mev, which could be useful in determining energy gaps on ti surfaces. interference effects are obvious in css from quasiparticle scattering off two scattering centers, and additional resonance peaks are introduced in a(tot) around similar to 233 mev associated with higher-order partial-waves.
