We have identified the main scattering channels when a molecular beam containing hyperthermal O and O2 strikes a FiberForm network, and we have obtained translational energy distributions of scattered products as well as temperature-and angle-dependent distributions of product flux. The analysis of the new data on FiberForm revealed chemical processes for which signatures were seen from vitreous carbon but were not analyzed in detail. Hence, in addition to analyzing the FiberForm results, we have also re-analyzed vitreous carbon data to facilitate an indepth comparison between the scattering dynamics of O and O2 on FiberForm and vitreous carbon, both of which are expected to have local surface sp 2 carbon structures that are rough on an atomic scale.
