Query: Non-Fermi Liquid Behavior in Dilute Quadrupolar System
  Pr$_{x}$La$_{1-x}$Pb$_3$ with $x$$\le$0.05   We have studied the low-temperature properties of Pr$_{x}$La$_{1-x}$Pb$_{3}$
with non-Kramers $\Gamma_{3}$ quadrupolar moments of the crystal-electric-field
ground state, for a wide concentration range of Pr ions. For $x$$\le$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 $\rho$$(T)$ in the corresponding temperature
region shows a marked decrease deviating from a Fermi-liquid behavior
$\rho$$(T)$$\propto$$T^{2}$. The Kondo effect arising from the correlation
between the dilute $\Gamma_{3}$ moments and the conduction electrons may give
rise to such anomalous behavior.
