Photoelectron angular distribution patterns from a single-crystal Cu(001) surface have produced dips, or silhouettes,'' in the low-energy, electron angular distribution measured around normal emission---a forward-scattering geometry that at higher energy produces a peak, or enhancement, in electron intensity. We have measured isoenergetic [ital l]=1 and [ital l]=2,0 photoelectrons that give different angular distribution patterns. These differences, and the low-energy electron intensity attenuation, are consistent with an electron scattering model that relies on the orbital angular momentum final-state dependence of the diffracting electron.
