  Title: ASCA OBSERVATIONS OF X-RAY SELECTED HIGH-REDSHIFT (Z                            


Abstract:
 ASCA has observed several high-z radio-loud quasars, and obtained good quality
 spectra of these objects (e.g. Siebert et al. 1995, Cappi et al. 1995). However, no
 spectral information is available so far for the high-z radio-quiet quasars. We
 propose to observe 3 X-ray selected high-z (z>2) radio-quiet quasars in order to
 fill this gap. The scientific goals of the proposal are: i) provide good constraints
 on the spectral parameters (Nh, photon index and FeK line parameters) of the quasars
 and ii) compare these results with those obtained for low-z radio-quiet quasars and (high-z and low-z) radio-loud quasars.
