****************************************************** PR # 11154 We propose to use ASCA to observe the brightest radio quiet QSO at redshift greater than 1 to search for the reflection signatures, an iron line and reflection hump,present in lower luminosity,nearby AGN. The high sensitivity of ASCA means that reasonable spectra can be obtained in 40ks, and at high zthe reflection hump is redshifted into the ASCA bandpass. These observations offer an opportunity to probe the accretion flow in high redshift QSO and test evolutionary theories. ******************************************************
