ABSTRACT
We present the results of spectral fits made to 57 pointed observations of the Galactic
black hole candidate and X-ray transient XTE J1650?500, made with the Rossi X-ray
Timing Explorer in 2001 when the source was in a transition from the hard state to the
soft state. A strong and variable Fe Kα emission line is detected in these spectra. The
line flux varies in a non-linear way with the hard X-ray flux, in apparent contradiction
to the predictions of simple disc reflection models. We observe a change in the overall
trend that coincides with changes in the continuum X-ray spectrum and the fast X-ray
variability. The Fe-line flux versus hard X-ray flux variations are consistent with the
predictions of reflection models which consider high disc-ionization states and with
a model which considers gravitational light-bending effects. Indications for an anti-
correlation between the Fe-line flux and the hard X-ray flux in the spectrally hardest
observations and weak variations in the Fe-line energy (as observed with XMM-Newton
and BeppoSAX) slightly favour the light-bending interpretation.
