Abstract

Recently, we have proposed s + g-wave superconductor in order to describe unusual superconductivity in borocarbides YNi₂B₂C and LuNi₂B₂C. Here we consider the effect of impurity scattering in the s + g-wave superconductors. The impurity scattering is studied within Born approximation. We find that the quasiparticle density of states is extremely sensitive to the small impurity scattering.
