We have applied the tool of resonant photoemission at the L3 absorption edge to thin Mn layers deposited on Cu(100). This allows us to study the transition from atomic to solid-state phase by following the 3d-band formation through the localization of a photon-excited electron in the presence of a 2p core hole. We have observed localized behavior for one of the transitions of the Mn 2p3p3d decay above the L3 absorption threshold for coverages smaller than 0.5 ML. We show that the autoionization time of the 2p-core-hole intermediate state is comparable to the time of localization of the photon-excited 3d electron in the presence of the 2p core hole in the case of the highest binding-energy transition of the 2p3p3d decay.

Abstract
We have applied the tool of resonant photoemission at the L3 absorption edge to thin Mn layers deposited on Cu(100). This allows us to study the transition from atomic to solid-state phase by following the 3d-band formation through the localization of a photon-excited electron in the presence of a 2p core hole. We have observed localized behavior for one of the transitions of the Mn 2p3p3d decay above the L3 absorption threshold for coverages smaller than 0.5 ML. We show that the autoionization time of the 2p-core-hole intermediate state is comparable to the time of localization of the photon-excited 3d electron in the presence of the 2p core hole in the case of the highest binding-energy transition of the 2p3p3d decay.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
