  Title: THE NARROW-LINE QUASAR IRAS 20181-2244: AN EXAMPLE AGAINST THE UNIFIED SCHEME ? 


Abstract:
 We propose to observe a narrow-line quasar IRAS 20181-2244. The luminosity of the
 galaxy is comparable to that of QSOs both at optical and X-ray region, and its
 luminosity ratio of X-ray to infrared is typical of those of bare AGNs. However its
 optical spectrum is typical of Seyfert 2s. If the AGN is obscured as predicted in
 the unified scheme of AGN, its intrinsic X-ray to infrared luminosity ratio becomes
 unbelievably large. The current observation is to test if there is a indded buried
 AGN in this galaxy. This is a crucial test for the unified scheme of AGN; are all
 type 2 AGN indeed obscured type 1s or are there two types of Seyfert 2s; those with
 obscured broad line regions (BLRs) and those without BLRs ?
