Scientific paper

We investigate the generation of emission lines via recombination and reflection due to resonance scattering, in the transition layers overlaying the surface of X-ray illuminated accretion disks. Our results show that the equivalent widths (EW) of the emission and scattering lines from such transition layers are generally less than 1 eV. Resonant line scattering plays an important role, the reflected line strengths are comparable with those of the emission lines when there is no intermediate stable layer. The detectability of such line features with Chandra is marginal if the illuminating continuum is in the direct view. However, if the continuum is obscured as in Seyfert 2 galaxies, these features should be observable.
