“…The b σ −10 cross sections measured by Risley and Geballe [16] (shown also in figure 4) have been previously used as our calibration experiment [20]. The reason for using this cross section to calibrate stems from its decreasing behavior as a function of the kinetic energy.…”

We present measured electron detachment cross sections from hydrogen anion induced by collisions with O 2 in the energy range of 1 to 9 keV with two methods, the beam attenuation and the signal growth rate. Processes involved in the interaction are discussed in terms of the cross section differences as a function of the time of flight of the H − through an analysing electric field. As a consequence, an ansatz value of the life-time for the auto-detaching states of H − population of 39 ± 12 ns is derived that is consistent with predictions for the lifetime of the (2p 2 ) 3 P state of H − .

“…The present experimental method has been previously described [20] 3 Here, we provide a description relevant to the present study. The method consists of a monoenergetic H − ion-beam interacting or colliding with pressure-controlled high purity O 2 gas contained in a gas-cell.…”
