摘要：

For pairing potentials which act only in the vicinity of the Fermi-surface, a Fermi-surface harmonics expansion of the gap function is appropriate. After a general symmetry discussion, it is pointed-out that the first extended s-wave occuring in the Fermi-surface harmonics expansion of the gap function a) is closely related to the usual d-waves b) it can have a large number of nodes. This may reconcile the experiments which see nodes in the gap and neutron-scattering experiments which cannot resolve the anistropy in the gap function.
