Fragmentation patterns of doubly charged acrylonitrile molecule following carbon core ionization

Dissociation of acrylonitrile into pairs of cations and neutral fragments following molecular core ionization was investigated using the photoelectron-photoion-photoion coincidence (PEPIPICO) technique. The fragment ion mass spectra were recorded in coincidence with the carbon 1s photoelectrons. Deuterated and (13)C-substituted samples were used for resolving fragment mass ambiguities. Slope analysis of the PEPIPICO patterns was used in determining the fragment separation sequences in case of multiparticle processes. The results show that there are several fragmentation channels producing a wide range of charged coincident fragments. The dynamics of the dominant fragmentation processes is investigated in detail.

Normal Auger spectra of Br in alkali bromide molecules

Molecular Auger electron spectra following the bromine 3d ionization in gas-phase alkali bromides and in HBr were studied both experimentally and theoretically. The AES for HBr and CsBr were measured using photoexcitation, and for LiBr, NaBr, and KBr by using electron impact. These results are compared with the theoretical spectra from nonrelativistic ab initio calculations and one-center approximation and with the spectra of Br(-), computed with the multiconfiguration Dirac-Fock method.

VUV excitation and electronic decay of rubidium halide molecules

Previously we reported an interionic Auger decay following the VUV resonant excitations of the metal atom in the alkali halide molecules. Opening and closing of the spectator Auger decay channel was found to strongly influence the lineshape of the participator decay transitions, an effect attributed to the changes in the lifetime of the VUV-excited state. In this work, the VUV excitation and the following electronic decay of the resonant states of rubidium halides is studied. A series of electron spectra have been measured at photon energies around the 4p → nl resonance excitation region. Experimental results and the theoretical modelling of the excitation and decay spectra are presented.

Smart Energy Networks in the Northern Periphery: Development of an End-User Oriented Profiled Hybrid Micro-Grid Simulator

Abstract In the presented work, a hybrid micro-grid simulator has been developed from the end-user point of view. The hybrid model includes a number of selectable elements for the production and storage of energy, making a (smart) use of the available renewable energy resources based on a demand-response principle. The main role of the simulator is to model the communication with the common energy network on case of surplus or deficit of energy production.
