We have extended our ESR study of Gd in the intermetallic compound Gd/sub x/La/sub 1-x/Pd/sub 3/ to samples annealed at 940 /sup 0/C and cooled rapidly to room temperature. We have measured the ESR linewidths and g shifts as a function of temperature and concentration of Gd. They were found to exhibit Korringa-like thermal broadening between 6 and 40 /sup 0/K. We have deduced the average value of J/sub eff/ for the effective-exchange integral to be 0.24 +- 0.03 eV. We have calculated also the magnitudes of the conduction-electron relaxation rates to the lattice, (i) due to the undisturbed host lattice, (ii) by spin-flip scattering due to the magnetic impurity Gd, and (iii) by spin-flip scattering due to the nonmagnetic impurity Th.
