We conducted optical investigations on the U{sub 1{minus}{ital x}}Th{sub {ital x}}Pd{sub 2}Al{sub 3} (0{lt}{ital x}{lt}0.9) system over a broad frequency range from 15 to 10{sup 5} cm{sup {minus}1}. We evaluated the frequency dependence of the scattering relaxation rate at various temperatures, from which we have characterized the evolution from a Fermi-liquid ground state for {ital x}{lt}0.2 to a non-Fermi-liquid ground state for 0.4{lt}{ital x}{lt}0.9. {copyright} {ital 1996 The American Physical Society.}
