Description
  • Reakce uhlovodíkového dikationtu C4H32+ s řadou atomových a molekulových terčových částic byly sledovány metodou roztylu ve zkřížených paprscích částic a metodou vedených paprsků. Byl pozorován nedisociativní přenos náboje, vedoucí k produktu C4H3+, a reakce přenosu protonu, vedoucí k produktu C4H2+ . V několika studovaných soustavách byl však pozorovám také disociativní přenos náboje, který podstatně přispíval k tvorbě produktu C4H2+. Z rozdělení translační energie produktů bylo možno učinit závěry o elektronických stavech uhlovodíkových kationtů, vznikajících v těchto reakcích. (cs)
  • Reactions of the hydrocarbon dication C4H32+ with a series of atomic and molecular targets (Kr, Xe, N-2, NO, NH3, C2H2, and CH4) were investigated in crossed-beam scattering and guided-beam (quadrupole-octopole-quadrupole, QOQ) experiments. Non-dissociative charge transfer (NDCT), leading to the product ion C4H3+, and proton transfer (PT), leading to the product ion C4H2+, were observed. In several systems, however, dissociative charge transfer (DCT) contributed significantly to the formation of the product ion C4H2+. Full scattering diagrams of the products C4H3 and C4H2+ were obtained for the reaction with acetylene. For the other systems, energy profiles of the products close to the angular maximum were obtained. The hydrocarbon products C4H2+ and C4H3+ were scattered mostly forward, suggesting an impulsive mechanism of their formation at the collision energies investigated; ...
