  Title: SERCH OF X-RAY REFLECTION NEBULA                                                


Abstract:
 G 7.4-1.4, G 14.2+0.1 and G 359.1-0.9 are diffuse X-ray sources discovered with
 Rosat. These are peculiar because they are not bright radio sources. Since the
 galactic Ridge spectrum shows strange feature 9very broad emission line at 1.8 and
 6.7 keV) which has not been found in any known X-ray objects, we propose to observe
 unknown objects as possible candidate. Also these sources lie near the bright
 sources GX 5-1 and GX 13+1. We will search for reflected X-ray flux from the bright
 source. Particular interest is in the 6.4 keV line emission.
