  We present high spectral-resolution optical spectra of 49 Herbig Ae/Be stars
in a search for the [O I] 6300.2 A line. The vast majority of the stars in our
sample show narrow (FWHM < 100 km/s) emission lines, centered on the stellar
radial velocity. Some stars in our sample show double-peaked lines profiles,
with peak-to-peak separations of about 10 km/s. The presence and strength of
the [O I] line emission appears to be well correlated with the far-infrared
energy distribution of each source: stars with a strong excess at 60 micron
have in general stronger [O I] emission than stars with weaker 60 micron
excesses. We interpret the observed [O I] 6300.2 A line profiles as arising in
the surface layers of the protoplanetary disks surrounding Herbig Ae/Be stars.
