Brill-Noether theory of curves on Enriques surfaces, II. The Clifford index

Abstract

We complete our study of linear series on curves lying on an Enriques surface by showing that, with the exception of smooth plane quintics, there are no exceptional curves on Enriques surfaces, that is, curves for which the Clifford index is not computed by a pencil.
