   Narrow Line Seyfert 1 (NLS1) galaxies lie at the extreme of the
   Seyfert 1 pheonomenon, exhibiting rapid variability, distinctive soft
   X-ray spectral complexity and narrow optical/UV emission lines. The
   reason for this unique behavior has not been identified, quite
   possibly because no NLS1 has yet been observed in the hard X-rays. We
   propose a 50 ks ASCA observation of the bright NLS1 Akn 564, to be
   coordinated with an already approved XTE observation. This will give
   the only 0.4--30 keV spectrum of a NLS1, allowing measurement of the
   iron line and reflection component and modeling of the complex soft
   X-ray spectrum, for comparison with normal Seyfert 1s. These data
   will also allow comparison of hard and soft component variability and
   compactness.
