摘要：
We calculated the spin susceptibility and self-energy for the 2D symmetric Anderson lattice model in a conserving approximation. The susceptibility rises with decreasing temperature to reach a maximum and then drops abruptly, and the density of states shows a crossover from metallic behavior at high temperatures to insulating behavior at low temperatures.
