  We report on the theoretical description of secondary electron emission due
to resonant charge transfer occurring during the collision of metastable
nitrogen molecules with dielectric surfaces. The emission is described as a two
step process consisting of electron capture to form an intermediate shape
resonance and subsequent electron emission by decay of this ion, either due to
its natural life time or its interaction with the surface. The electron capture
is modeled using the Keldysh Green's function technique and the negative ion
decay is described by a combination of the Keldysh technique and a rate
equation approach. We find the resonant capture of electrons to be very
efficient and the natural decay to be clearly dominating over the
surface-induced decay. Secondary electron emission coefficients are calculated
for aluminum oxide, magnesium oxide, silicon oxide, and diamond at several
kinetic energies of the projectile. With the exception of magnesium oxide the
coefficients turn out to be of the order of 0.1 over the whole range of kinetic
energies. This rather large value is a direct consequence of the shape
resonance acting as a relay state for electron emission.
