 Abstract: We have measured the thermal conductivitiesK s in the superconducting state andK n in the normal state of (La1−x REx) Al2 single crystals (RE: Gd, Ce;x≦0.005) between 0.4 and 8 K. The lattice conductivity is small in the superconducting state above 0.5T c and in the normal state and is independent of annealing. Annealing does, however, strongly depress the ratioK s e /K n e of the electronic thermal conductivities. We also report on a theory of the electronic thermal conductivity which describes the experimental results quantitatively. Interaction effects between impurities show up for the samples with the highest RE-concentration.
