Double photoemission from fullerene films: angular photoelectron distributions and continuum resonant states. — •Oleg Kidun1, Jamal Berakdar2, and Natalia Fominykh2 — 1Max-Planck-Institut fuer Kernphysik, Heidelberg, — 2Max-Planck-Institut fuer Mikrostrukturphysik,
Angular distributions of the emission probability (ADP) of correlated electron pairs from 2D fullerene lattices upon absorption of a single photon are investigated. We found drastic changes of these angular emission patterns within the narrow photon energy region in the vicinity of the ionization threshold. The connection of the ADP structure with the presence of continuum resonant states of the film is discussed. The manifestation of resonant states in the energy spectrum and their decay in time are studied in detail. [1]
