   AX J1842.8-0423 and RXJ1802.1+1804, observed with ASCA in 1996, exhibit
   a strong Fe-K line with an extremely large equivalent width 4000 eV
   .These objects are thought to be magnetic white dwarf binary, so called
   Polar(or AM Herculis object). The accretion column of a magnetized
   white dwarf is usually quite opaque to resonance scattering for Fe-K
   line.So, we consider, in some extraordinary condition, Fe-K line photon
   will be collimated strongly by resonance scattering.Our proposal is to
   observe Polars with pole-on inclination angle, and to test this beaming
   effect of Fe line.
