Title:
State-selective charge transfer in slow collisions of O^{3+} with H and H_{2}
Abstract:
We have used photon emission spectroscopy to determine absolute, state-selective cross sections for single-electron capture by O^{3+} ions colliding on atomic and molecular hydrogen. The impact energy was varied between 45 and 752 eV amu^{-1}. For collisions we find that the cross section for capture into the 2p3s state of O^{2+} strongly increases with impact energy up to an energy of ~ 100 eV amu^{-1}. At higher impact energies the 2p3s cross section becomes comparable to the more or less constant 2p3p cross section. For the O^{3+} + H_{2} system these state-selective cross sections both stay approximately constant over the entire energy range investigated. Our results will be compared with existing experimental and theoretical data.
