   PR # 42181
   We propose ASCA spectra for six X-ray clusters of galaxies with
   cooling flows. The primary aim is to determine the physical state and
   ultimate repository of the gas cooling in these systems. We will use
   emission line diagnostics to derive the amount and spatial
   distribution of the cooling material, and the density structure of
   inhomogeneities. Previous Einstein or ROSAT spectra of these clusters
   show evidence for excess X-ray absorption. The presence of this
   excess soft X-ray absorption will be verified, and we will determine
   if it is intrinsic to the cluster or in the foreground. The spatial
   distribution of this cold material will be derived. We will also
   determine overall cluster properties, such as the gas temperature and
   density profiles and the amount and distribution of dark matter.
