****************************************************** PR # 31190 We propose an ASCA observation of the ultraluminous infrared galaxy I RAS110548-1131 in which broad Ha (FWHM 7,600km/s) was found in the po larized flux spectrum. This object is classified as a Seyfert 2. Howe ver, the polarized BLR suggests the heavy nuclear obscuration and tha t its radiation of the hidden nucleus would be electron-scattered int o the line of sight. This object could be one of the nearest quasar which emit an intrinsic luminosity of Lx=10^45 erg/s, and then we can expect the extremely large EW of the He-like Fe K line (EW = 2-3keV ) on the scattered continuum of the hidden quasar nucleus, because o f its higher luminosity than nearby Seyfert 2s with much lower lumino sities. ******************************************************
