We discuss two recent topics on heavy‐ion quasi‐elastic scattering at energies around the Coulomb barrier. The first topic is an application of quasi‐elastic scattering at deep‐subbarrier energies to extracting the surface diffuseness parameter of the nucleus‐nucleus potential. The second topic is a coupled‐channels analysis for the quasi‐elastic barrier distribution for the 70 Zn + 208 Pb reaction. We show that the coupled‐channels calculations which include the multi‐phonon excitations in the colliding nuclei reproduce reasonably well the experimental excitation function for quasi‐elastic scattering at backward angles and the barrier distribution for this reaction.
