A self-energy approximation is applied for obtaining the electronic structure of these two superconducting heavy-fermion systems and we explain some of their main experimental features by analyzing the calculated total and partial density of states. The superconducting mechanism is discussed and we determine relations between the density of states and the superconducting parameters.
