摘要：

We demonstrate that the angular distribution of electrons photoemitted from image states on a clean metal surface depends on the energies associated with the final electronic motion normal, E-z, and parallel, E-parallel to to the surface. The surface normal (z) over cap is the most probable direction of ionization when E-z much greater than E-parallel to. But, for E-z approximate to E-parallel to, many electrons are ejected away from (z) over cap and the pattern of emission is altered dramatically. If a pump laser pulse produces a superposition of two image states, then the intensity and in certain cases the direction of photoemission from this wave packet can be coherently controlled via a probe pulse.
