  We present the single stellar population (SSP) synthesis results of our new
synthetic stellar atmosphere models library with a spectral sampling of 0.3 A,
covering the wavelength range from 3000 A to 7000 A for a wide range of
metallicities (twice solar, solar, half and 1/10 solar). The stellar library is
composed of 1650 spectra computed with the latest improvements in stellar
atmospheres. In particular it incorporates non-LTE line-blanketed models for
hot (Teff >= 27500 K) and LTE line-blanketed models (Phoenix) for cool (3000 K
=< Teff =< 4500 K) stars. Because of the high spectral resolution of this
library, evolutionary synthesis models can be used to predict the strength of
numerous weak absorption lines, and the evolution of the profiles of the
strongest lines over a wide range of ages. The SSP results have been calculated
for ages 1 Myr to 17 Gyr using the stellar evolutionary provided by the Geneva
and Padova-tracks groups. For young stellar populations, our results have a
very detailed coverage of high-temperature stars with similar results for
Padova and Geneva isochrones. For intermediate and old stellar populations, our
results, once degraded to a lower resolution, are similar to the ones obtained
by other groups apart from limitations imposed by the stellar evolutionary
physics. The limitations and advantages of our library for the analysis of
integrated populations are described. The full set of the stellar library and
the evolutionary models are available for retrieval at the websites
http://www.iaa.csic.es/~rosa and http://www.iaa.csic.es/~mcs/Sed@, or on
request from the first two authors.
