“…Other studies have observed similar effects in CuO [4] and NiO [6], with either a microscopic resonant photoemission theory [2][3][4] or a macroscopic resonant x-ray optical theory [2,3,6] being able to explain the data. However, beyond these studies are others [7][8][9][10][11][12][13] which have seen such effects in both valence photoemission [7][8][9] and adsorbate emission [10] and claim not to have seen MARPE in x-ray emission and photoemission [11][12][13]. Thus, the experimental results overall leave controversy, with some authors reporting that they were able to observe MARPE, but on the other hand some other authors insist that they were not, which also stimulates several theoretical studies [14,15].…”

Interatomic resonant Auger can take place when the photon energy is tuned to a resonant core-level excitation of an atom neighbouring the emitting atom, with the emitting core-level having a lower binding energy than the resonant core-level. This phenomenon in a hetero-nuclear diatomic molecule has been demonstrated for the first time as the intensity enhancement of the lower core-level photoemission. Such a phenomenon should be considered to be general and then the present results in the simplest system open a door to a new horizon of photoemission studies for both isolated molecules and condensed systems including different atoms.

“…More specifically, both the microscopic resonant photoemission model and the RXRO model are found to well reproduce experimental data observed for the case of O 1s emission from MnO 7 on passing the Mn 2p 1/2,3/2 resonances, with the microscopic model also having been shown to explain analogous data for O 1s emission from CuO on passing the Cu 2p 1/2,3/2 resonances 11 . In a more recent study of MARPE effects for N 2 adsorbed on Ni(111), it has been found that N 1s emission on passing the Ni 2p 1/2,3/2 resonances also can be described in terms of the RXRO model 12 ; although this study also attempted to observe short-range MARPE effects that went beyond the RXRO picture, these were not found, at least to within ∼1% in magnitude.…”

ABST RACTWe present experimental and theoretical results for the variation of the O 1s intensity from a NiO(001) surface as the excitation energy is varied through the Ni 2p 1/2,3/2 absorption resonances, and as the incidence angle of the radiation is varied from grazing to larger values. For grazing incidence, a strong multi-atom resonant photoemission (MARPE) effect is seen on the O 1s intensity as the Ni 2p resonances are crossed, but its magnitude decreases rapidly as the incidence angle is increased. Resonant x-ray optical (RXRO) calculations are found to predict these effects very well, although the experimental effects are found to decrease at higher incidence angles faster than those in theory. The potential influence of photoelectron diffraction effects on such measurements are also considered, including experimental data with azimuthal-angle variation and corresponding multiple-scatteringdiffraction calculations, but we conclude that they do not vary beyond what is expected on the basis of the change in photoelectron kinetic energy. Varying from linear polarization to circular polarization is found to enhance these effects in NiO considerably, although the reasons are not clear. We also discuss the relationship of these measurements to other related interatomic resonance experiments and theoretical developments, and make some suggestions for future studies in this area.2

“…Although some first measurements and discussions of the effects were influenced by the nonlinearity of a particular detector system utilized [1,3], it has subsequently been shown that the experimental MARPE effects can be predicted with 0953-4075/13/115101+10$33.00 either a microscopic resonant photoemission theory [2][3][4] or a macroscopic resonant x-ray optical theory [2,3,6]. However, the experimental results overall leave controversy [7][8][9][10][11][12][13], with some authors reporting that they were able to observe MARPE [7][8][9][10], but on the other hand others insisting that they were not [11][12][13], which also stimulated several theoretical studies [14,15]. MARPE can be considered as an interatomic resonant Auger (IARA) process in the field of molecular physics.…”

Core-level interatomic resonant Auger in isolated molecules can take place when the photon energy is tuned to a resonant core-level excitation of an atom neighbouring the electron-emitter atom, provided that the emitter atom has smaller ionization energy of core electrons than the resonant energy. A multi-atomic nature of the Auger is a molecular analogue of multi-atom resonant photoemission (MARPE) observed in a condensed phase. This phenomenon in linear molecules, NO and CS 2 , has been explored by means of a photoelectron-fragment-ion-fragment-ion multi-coincidence velocity mapping technique. The N 1s (S 2p) photoionization experiments have been conducted at the O 1s → π * (C 1s → π * ) resonance energy and at the off-resonance one, in which photoelectron angular distributions were obtained with respect to the recoil axis of the fragment ions produced by an Auger decay following the core-level photoemission. A resonance enhancement was observed along the photon polarization direction and this effect strongly depends on the relative geometry of the polarization vector and the recoil axis. By comparing the N 1s photoemission of NO with the S 2p photoemission of CS 2 , it is shown that the resonance enhancement also depends on the core-orbital characters that participate in the process. Such phenomenon should be considered to be general and the present results of the simplest system thus shed new light on photoemission studies for both isolated molecules and condensed systems consisting of different elements.
