We investigated the correlation between initial sticking coefficient and O$$_{2}$$ transitional kinetic energy to understand O$$_{2}$$ adsorption processes on the Ti(0001) surface via photoemission spectroscopy for O-1s and Ti-2p core levels using the surface reaction analysis apparatus, installed at the JAERI soft X-ray beamline BL23SU in the SPring-8. We observed the decrease of initial sticking coefficient of O$$_{2}$$ molecules on the Ti(0001) surface with increasing O$$_{2}$$ transitional kinetic energy. We concluded that the O$$_{2}$$ adsorption on the Ti(0001) surface proceeded by a trapping-mediated dissociative adsorption mechanism. The constant dependence of the initial sticking coefficient on incident angle of O$$_{2}$$ beams also suggested the propriety of the trapping-mediated surface reaction mechanism.
