abstract = {The hydrocarbon fluxes released from a hydrogenated
graphite surface due to thermal erosion and chemical
sputtering become subject to a number of particle-surface
interaction (PSI) processes in the near-surface region.
These processes involve an electron transfer between the
released particle and the surface and, thus, affect the
charge state distribution of released hydrocarbons. The
electron capture from the surface by a hydrocarbon ion to an
excited dissociative state can lead to prompt dissociation
of the formed molecule, producing two (or more) lighter
fragments. These PSI processes (of resonant and Auger type)
have so far not been included in the plasma-wall interaction
studies. It is, however, obvious that they play a decisive
role in determination of chemical composition and charge
state distribution of hydrocarbon fluxes released from the
surface and entering the edge/divertor plasma region. It is
equally obvious that the same processes also take place when
the hydrocarbon species approach the graphite surface from
the interior of the edge/divertor plasma region, thus
affecting their sticking to the surface.},
