We have studied the low-temperature properties of Prx La1 - x Pb3 and Prx La1 - x InAg2 with the crystal-electric-field ground state of a non-Kramers Γ3 doublet to examine the correlation between the Γ3 quadrupolar moments and the conduction electrons. In Prx La1 - x Pb3, a non-Fermi-liquid (NFL) behavior is observed for x {less-than or slanted equal to} 0.05 in the specific heat C / T and the electrical resistivity below 3 K. Moreover, application of magnetic field raises C / T rapidly, which demonstrates the presence of the residual entropy at lower temperatures. In Prx La1 - x InAg2, NFL behavior is confirmed up to x=0.8 in the susceptibility and the specific heat below 15 K. It is supposed that the Kondo effect arising from the correlation between the dilute Γ3 moments and the conduction electrons gives rise to NFL behavior in both systems.
