We have studied the low-temperature properties of PrxLa 1-x,Pb3 with non-Kramers Γ3 quadrupolar moments of the crystal-electric-field ground state, for a wide concentration range of Pr ions. For z ≤ 0.05, the specific heat C/T increases monotonically below T = 1.5 K, which can be scaled with a characteristic temperature T* defined at each concentration x. The electrical resistivity ρ(T) in the corresponding temperature region shows a marked decrease deviating from a Fermi-liquid behavior ρ(T) ∝ T2. The Kondo effect arising from the correlation between the dilute Γ3 moments and the conduction electrons may give rise to such anomalous behavior.
