****************************************************** PR # 41185 We propose a 100ks ASCA observation of the Seyfert 2 galaxy NGC1068. The ASCA PV observation revealed that the soft X-ray emission is dominated by starburst emission, and the scattered AGN emission appears above 3 keV. The prominent iron K line complex, which consits at least 3 components, are emitted from the scattering matter. A recent improved analysis shows eveidence for the Compton shoulder at the base of 6.4 keV line, which implies the line is scattered by Compton-thick cold matter. Contrary to this, the higher energy lines are believed to be emitted from warm, optically thin gas. This proposed long observation provides precise measurements of the Compton shoulder and the other line components to study detailed physical condition of the nuclear matter in Seyfert 2 nuclei. ******************************************************
