Electron capture in H{sup +}{sub +}O{sub 2} is studied at low keV energies and scattering angles 0<{theta}<1 deg. Time-of-flight techniques are used to identify the states excited. Using the H{sup +}{sub +}H{sub 2} collisions as an energy reference our results to date show that at an energy E=1.0 keV the ground state, H(1s)+O{sub 2}{sup +}(X), channel is dominant only for {theta}<0.3 deg. At a scattering angle of 1.0 deg the probability for capture into the ground state is 0.3. This channel is exothermic by Q=-1.5 eV and is excited via a vertical transit on second important process resulting in H(1s)+O{sub 2}{sup +} also found at small scattering angles. Other-channels are seen at larger angles in the range investigated. Additional results will be presented and interpreted.
