Abstract
We prove that every irreducible component of semi-regular loci of effective line bundles in the Picard scheme of a smooth projective variety has at worst rational singularities. This generalizes Kempf's result on rational singularities of Wd0 for smooth curves. We also work out an example of such loci for a ruled surface.
