  Title: X-RAY SPECTRUM OF THE HIGH REDSHIFT QUASAR HE 1104-1805                         


Abstract:
 We propose to observe HE 1104-1805, a high redshift (z=2.3) radio-quiet quasar which
 is gravitationally lensed. The two lensed images are within 3 arcsec of each other
 and have been detected as an extremely bright source in the ROSAT PSPC. HE 1104-1805
 provides a unique opportunity to observe a relatively low luminosity, radio-quiet
 quasar at high redshift, in contrast to all other z>2 quasars previously studied
 with ASCA, which are radio-loud.
