  Using exact diagonalization techniques we study the dynamical response of the
anisotropic disordered Heisenberg model for systems of S=1/2 spins with
infinite range random exchange interactions at temperature T=0. The model can
be considered as a generalization, to the quantum case, of the well known
Sherrington-Kirkpatrick classical spin-glass model. We also compute and study
the behavior of the Edwards Anderson order parameter and energy per spin as the
anisotropy evolves from the Ising to the Heisenberg limits.
