  A general partial-wave multiple scattering theory for scattering from
cylindrically symmetric potentials on a topological insulator (TI) surface is
developed. As an application, the cross sections for a single scatterer and two
scatterers are discussed. We find that the symmetry of differential cross
section is reduced and the backscattering is allowed for massive Dirac fermions
on gapped TI surface. Remarkably, a sharp resonance peak at the band edge of
the gapped TI is found in the total cross section $\Lambda_{tot}$, which may
offer a useful way to determine the gap (as well as the effective mass of
quasiparticles) on TI surface. We show that the interference effect is obvious
in cross sections during the quasiparticle scattering between the scatterer
pair, and additional resonance peaks are introduced in $\Lambda_{tot}$ when the
higher partial waves are taken into account.
