The inner-valence Auger electron spectra after the chlorine 2p ionization in the gas phase CHCl3 molecule were investigated both theoretically and experimentally. The total ion yield spectrum exhibits a broad structure at 217 eV, above the Cl 2p ioni

We investigate the formation of Au structures by continuing fragmentation of a Au film separated from Si (100) substrate by a Ti adhesion layer. The ion-beam processing uses 2 keV Cs+ projectiles. It induces the formation of a large variety of struct

We reveal early stages of self-organization of nanopatterns created by 2 keV Cs+ ion-beam irradiation of a Si surface coated with Au and a Ti adhesion layer. After ion-beam etching of the metallic layers, at normal incidence, we first observe distinc

The dynamics of the photofragmentation pathways of tetrachloroethylene with photon energies from 15 up to 250 eV encompassing the Cl 2p edge is presented. In order to distinguish the fragmentation channels, the ionic fragments were separated accordin

The Auger electron spectra after the chlorine 2p excitation and ionization in the gas phase CH2Cl2 and CD2Cl2 molecules were investigated both theoretically and experimentally. A series of high-level ab initio quantum mechanical calculations have bee

In this paper, the ultrafast dissociation following Cl 2p core–shell excitation into the 10a1* antibonding orbital in CH2Cl2 and CD2Cl2 molecules is studied. It is observed the presence of atomic Auger lines associated to the decay of dissociated C

In the present work, we use tunable synchrotron radiation to investigate experimentally and theoretically the dissociation of a chlorinated methane, the CHCl3 molecule, by exciting a chlorine 2p core electron into the LUMO and LUMO + 1 orbitals. The
