Abstract
Using Nagaoka's decoupled equations of motion for double-time Green's functions an approximate integral equation is derived and solved numerically for the self-energy of conduction electrons in intermetallic compounds containing a non-dilute and translationally symmetric system of magnetic rare-earth ions. These latter are assumed to interact with an antiferromagnetics-f exchange parameter with the conduction electrons. The resistivity is computed and compared with experimental values for CeAl2 and CeAl3.
