摘要：

We study the effect of the non-s-wave phase shifts of the impurity potential beyond the usual delta-function approximation in d-wave and anisotropic s-wave order parameters. We compute the density of states, superfluid density, transition temperature, and the magnitude of the gap in various situations. We also discuss how strongly the physical quantities depend on model parameters of the impurity potential.
