摘要：

We present the first 2.05-2.45 mu m spectra of the Galactic Bulge LMXBs GX1+4 and GX13+1. We report the detection of Brackett gamma emission from the accretion disc in both systems, confirming the identification of the infrared (IR) counterpart to GX13+1. Both spectra show CO molecular bands and metal lines in absorption, representing the first IR spectroscopic detection of the secondary in a heavily obscured bulge source. We have also obtained a JHK spectrum of the LMXB Sco X-1, which shows strong H I, He I, and He II emission.
