The symmetric periodic Anderson model is studied in the limit of infinite spatial dimensions within an essentially exact quantum Monte Carlo method. The single-particle spectral function develops a gap DELTA, and the neutron structure factor also develops a gap almost-equal-to 2DELTA. Depending upon the ratio of DELTA to other energy scales, there is a transition to an antiferromagnetic state. In the paramagnetic state, both the f orbital specific heat and ferromagnetic susceptibility display rough scaling with T/DELTA; for T > DELTA they are heavy-fermion-like while for T < DELTA they are insulatorlike.
