   We propose ASCA spectra for five X-ray clusters 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 of 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
   same imcludes moderate redshift cooling flow clusters with very strong
   optical line emission. We will also determine overall cluster
   properties, such as the gas temperature and density profiles and the
   amount and distribution of dark matter.
