    Utilizing the broad bandpass, large effective area, and high spectral
    resolution of the ASCA detectors, we propose to observe a small      
    sample of intermediate polars to determine the nature of their X-ray 
    spectra and thereby constrain the accretion geometry, and hence the  
    overall  model, of this class of magnetic cataclysmic variables.     
    Specifically, we propose to utilize spin-phase resolved spectroscopic
    obs of the O and Fe K-edges & the Fe L and K emission line complexes 
    to constrain (1) the ionization parameter of the high column density 
    of absorbing material along the line of sight to the X-ray source,   
    (2)the density and electron temperature of the photoionized gas, and 
    (3)the temperature and emission measure of the thermal gas behind the
   accretion shock.
