We have analyzed the RXTE PCA spectra of the June 1998 outburst of XTE J1748-288, and the May 2000 outburst of XTE J1550-564. We attempt to fit the reflection spectra of these sources self-consistently by allowing for fluorescent iron emission and disk reflection in our models. We resolve broad (0.2-0.8 keV, FWHM), redshifted Fe K-alpha lines (0.05-0.70 keV, EW) at 6.70+/-0.10 keV. We find evidence for small disk reflection fractions (0.0 <= f <= 0.45) from highly ionized disks (ξ >=104) in the spectra. Our results suggest that these sources may be well-described by Kerr geometries. We will discuss these finduings and possible implications for the accretion flow geometries in XTE J1748-288 and XTE J1550-564.
