抄録

The relative ionization probabilities of laser-detonation hyperthermal O, O 2 , and Ar components in Ar+O 2 mixed molecular beams were evaluated for investigation of the effect of the space environment. In a high-energy beam, the complete decomposition of O 2 was observed from the time-of-flight (TOF) spectra, which was due to high-energy collisions between O 2 and Ar. Relative ionization probabilities of O and O 2 of 0.27 and 0.79, respectively, with respect to Ar were evaluated by assuming the complete decomposition of O 2 in the beam. These values can be applied in studies on the effect of the space environment in the sub-low Earth orbit region where simultaneous hyperthermal N 2 and O bombardment should be simulated.
