  We present a numerical study of mixed boson-fermion systems at zero
temperature in isotropic and anisotropic harmonic traps. We investigate the
phenomenon of component separation as function of the strength of the
inter-particle interaction. While solving a Gross-Pitaevskii mean field
equation for the boson distribution in the trap, we utilize two different
methods to extract the density profile of the fermion component; a
semiclassical Thomas-Fermi approximation and a quantum mechanical Slater
determinant Schr\"{o}dinger equation.
