Electron impact iozization of CCl4 and SF6 embedded in superfluid helium droplets
PublicationElectron impact ionization of helium nano-droplets containing several 104 He atoms and doped with CCl4 or SF6 molecules is studied with high-mass resolution. The mass spectra show significant clustering of CCl4 molecules, less so for SF6 under our experimental conditions. Positive ion efficiency curves as a function of electron energy indicate complete immersion of the molecules inside the helium droplets in both cases. For CCl4...

Surface characteristics of glass fibres covered with an aluminum layer after a chemical modification process using secondary ion mass spectrometry (SIMS) and atomic force microscopy (AFM)
PublicationPrzedstawiono wyniki z badań powierzchni modyfikowanych włókien szklanych (przed i po procesie chemicznej modyfikacji ich powierzchni), które są kandydatem na przyszły oryginalny bezmatrycowy materiał odniesienia lotnych analitów etenu (C2H4) metodami spektrometrii mas jonów wtórnych oraz mikroskopii sił atomowych. Badania miały na celu obserwację zmian oraz procesów, jakie zaszły na powierzchni włókien szklanych pokrytych...

Vacuum ultraviolet photoionization and ionic fragmentation of the isoxazole molecules
PublicationThe photofragmentation of the isoxazole molecules producing ionized atomic and molecular fragments was investigated in the photon energy range of 9e32 eV, using synchrotron radiation excitation combined with ion time-of-flight spectrometry. Twenty-one well resolved cations were identified in the mass spectra of the isoxazole, and their appearance energies were determined. The yield curves of these cations were obtained in the photon...

Low energy electron attachment to platinum(II) bromide (PtBr2)
PublicationtDissociative electron attachment to PtBr2in the gas phase was studied in the low electron energy rangefrom zero up to 10 eV with an energy resolution of 150 meV. The experiments were carried out using ahemispherical electron monochromator coupled with a quadrupole mass spectrometer and pulse count-ing acquisition system. The only anion observed was Br−. This ion is formed at three resonance electronenergies: 0.4 eV, 1.2 eV and...

Electron impact ionization of CCl4 and SF6 embedded in superfluid helium droplets
PublicationBadana była jonizacja helowych nano-kropel o rozmiarach 104 z osadzonymi wewnątrz molekułami CCl4 i SF6. Zmierzone z dużą rozdzielczością widma masowe wskazują na tworzenie dużych klasterów w przypadku CCl4. Zależność intensywności jonizacji w funkcji energii wskazuje, że w przypadku obu molekuł osadzają się one wewnątrz kropli. Zaobserwowano jon macierzysty CCl4-, prawdopodobnie powstający na drodze jonizacji Penninga podczas...

Reactions in nanofilms of trifluoroacetic acid (CF3COOH) driven by low energy electrons
PublicationBadano modyfikacje chemiczne indukowane przez niskoenergetyczne elektrony (0-20eV) w cienkich warstwach skondensowanych molekuł CF3COOH. Do badań zastosowano dwie metody: desorpcję jonów w wyniku bombardowania elektronami (ESD - Electron Stimulated Desorption) oraz termiczną desorpcję jonów (TDS - Thermal Desorption Spectroscopy).

Dissociative multi-photon ionization of isolated uracil and uracil-adenine complexes
PublicationRecent multi-photon ionization (MPI) experiments on uracil revealed a fragment ion at m/z 84 that was proposed as a potential marker for ring opening in the electronically excited neutral molecule. The present MPI measurements on deuterated uracil identify the fragment as C3H4N2O+ (uracil+ less CO), a plausible dissociative ionization product from the theoretically predicted open-ring isomer. Equivalent measurements on thymine...

Dissociation and fragmentation of furan by electron impact
PublicationDissociation and fragmentation processes that produce electronically excited atomic and molecular fragments, following electron impact excitation, have been studied in furan. The optical excitation technique has been employed over the electron incident energy range 15-95 eV. Formation of excited hydrogen atoms H(n) in the n = 4-10 states has been detected by observation of the Balmer series. The diatomic CH fragments are formed...

PublicationPrzedstawiono reakcje indukowane przez niskoenergetyczne elektrony (0.7 - 20 eV) w kondensowanych warstwach kwasu mrówkowego (HCOOH), częściowo deuterowanego kwasu octowego (CH3COOD) oraz kwasu trifluorooctowego (CF3COOD).

Electron-impact ionization of fluoromethanes – Review of experiments and binary-encounter models
PublicationExperiments and recommended data on electron-impact ionization of methane and fluoromethanes (CH3F, CH2F2, CHF3, CF4) are reviewed and compared with binary-encounter models (Gryzinski’s, ´ Deutsch and Märk’s, and Kim and Rudd’s). A good agreement between recent experiments and the two latter classical-like models is shown. Kim and Rudd’s model (calculated presently in the restricted HartreeFock 6-31**G orbital basis) predicts well...
