  High resolution \'echelle spectra were obtained with the FEROS spectrograph
at the 1.5m ESO telescope for 35 nearby bulge-like stars with metallicities in
the range -0.8 $\leq$ [Fe/H] $\leq$ +0.4. Geneva photometry, astrometric data
from Hipparcos and radial velocities from Coravel are available for these
stars. From Hipparcos data it appears that the turnoff of this population
indicates an age of 10-11 Gyr (Grenon 1999).
  Detailed analysis of the sample stars is carried out and atmospheric
parameters derived from spectroscopic and photometric determinations are
presented. Oxygen abundances are derived based on the forbidden [O I] $\lambda$
6300.3 {\rm \AA} line. The results show an oxygen overabundance pattern for
most of the sample stars when compared to their disk counterparts.
