We investigate electronic states in the multichannel degenerate Anderson lattice with the aid of the 1/N-expansion procedure. Inclusion of the self-energy in O(N-0) leads to heavy electrons with degeneracy of channel and spin-orbit. In O(N-1); we find a T-linear term in the imaginary part of the self-energy of the conduction electrons at the Fermi level, in contrast to a T-2-term as in the Fermi liquid or a constant term as in the non-Fermi liquid found in infinite dimensions. The disappearance of the imaginary Dart at T = O is due to the intersite correlation effects that reflect the translational invariance. The Luttinger sum rule is proved to hold.
