Abstract
We analyzed the effect of nonmagnetic impurities in ci-wave superconductors with an energy dependent density of slates. Two singular forms for the den sity of states have been considered. The strength of singularity affect thr degradation of the critical temperature and reduces the pair-breaking effe ct.
