  Results from a study of Fe K-alpha emission lines for a sample of six
non-magnetic Cataclysmic Variables (CVs) using the high resolution X-ray data
from the Chandra High Energy Transmission Grating (HETG) are presented. Two of
the sources, SS Cyg and U Gem are observed in both quiescent and outburst
states whereas V603 Aql, V426 Oph, WX Hyi and SU UMa are observed only in
quiescence. The fluorescent Fe line is prominent in V603 Aql, V426 Oph and SS
Cyg during quiescence indicating the presence of a conspicuous reflection
component in these sources. The observed equivalent width of the fluorescent Fe
line is consistent with reflection from a white dwarf surface that subtends 2pi
solid angle at the X-ray source. During the outburst in SS Cyg, the fluorescent
line is red-shifted by about 2300 km/s. The Fe XXV triplet at 6.7 keV is found
to be dominant in all sources. The value of the G-ratio derived from the Fe XXV
triplet indicates that the plasma is in collisional ionization equilibrium
during the quiescent state. The Fe XXV line is significantly broadened in U Gem
and SS Cyg during the outbursts compared to quiescence, indicating the presence
of a high velocity material near the white dwarf during the outburst. The ratio
of Fe XXVI/XXV indicates a higher ionization temperature during quiescence than
in outburst in U Gem and SS Cyg.
