• The Anderson Hamiltonian with electron hole symmetry is investigated by the pertur-bation expansion in a power series of the electron correlation U. As it is found that expansions converge rapidly, we can draw continuous curves for the magnetic susceptibility χ, the T-Iinear specific heat C, the resistivity and density of states over the Hartree-Fock critical point. Moreover, it can be shown that there are some relations between physical quantities in this system. In particular, we show that the T-Iinear specific heat is proportional to the even part of the zero temperature susceptibility. Using the above relation, we can show the ratio π^2/3ル_B^2/μ_B^2. χT/C begins with unity and gradually tends to 2 with increasing U.
