Abstract
We analyze the phenomenon of particle creation in a cosmological anisotropic universe. We compute, via the Bogoliubov transformations, the density number of scalar and spin-1/2 particles created. We obtain that they are respectively described by Bose-Einstein and Fermi-Dirac distributions.
