Abstract
The direct-transition photoemission peak from the sp valence band of A g(lll) shows a pronounced asymmetry. The emission intensity on the low er binding energy side of this peak is considerably higher, and extend s to a cutoff at the band edge just below the Fermi level. This extra emission is derived from indirect transitions induced by the surface. A linear combination of the direct (bulk) and indirect (surface) chann els results in the asymmetric line shape.
