Abstract
We present spectroscopic observations of 36 asteroids, members of the Themis
family. These observations were carried on at the European Southern
Observatory in the wavelength range 
Å. Most of the objects present
a spectra similar to C-type asteroids and some of them present
indicative of aqueous alteration. We discuss the implications of these
results on the formation and evolution of this family.
Key words: minor planets, asteroids
Based on observations made with the 1.52 m telescope at the European Southern Observatory (La Silla, Chile) under the agreement with the CNPq/ Observatório Nacional.
