We investigate the binding energy separation between the many-body ground-state singlet and higher-lying magnetic states for the f'-f Anderson model to next-leading order in the 1 f N expansion, where N denotes the orbital degeneracy of the f states. We formulate inlegnl equations for the magnetic-state ampliludes that appear at next-leading order in I / N… (More)
