Absence of acoustic signature of the quadrupolar Kondo effect in U0.2Y0.8Pd3

Abstract
Elastic-constant data for U0.2 Y0.8 Pd3 are presented between 1.5 and 100 K. The absence of any strong anomaly in their temperature dependence is strong evidence against a quadrupolar Kondo effect interpretation of the non-Fermi-liquid behavior of this compound.
