  We report electromagnetically induced absorption (EIA) resonances of
sub-natural linewidth (FWHM) in metastable noble gas 83Kr* atoms using
degenerate two level schemes (DTLSs). This is the first observation of EIA
effect in a metastable noble gas atoms. Using these spectrally narrow EIA
signals obtained corresponding to the closed hyperfine transition from
4p55s[3/2]2 to 4p55p[5/2]3 hyperfine manifolds of 83Kr* atoms, we have measured
the Lande's g-factor (gF) for the lower level (F = 13/2) of the closed
transition accurately with small applied magnetic fields of few Gauss.
