Scientific paper

Fluorescent iron line models are applied to data of GX301-2 (Leahy et al., 1988) obtained by the Tenma satellite. It is found that a spherically symmetric fluorescence model well describes the dependence of equivalent width on column density. A decrease of fluorescence efficiency with increasing source intensity is observed, probably due to a luminosity-dependent accretion geometry. Correction of the equivalent widths for the luminosity-dependence is shown to improve agreement with the model.
