Popis:	The specific heat at a constant pressure (C p) and the velocity of sound (v) are measured for a moderate heavy-fermion compound YbZnCu4 in the temperature range 3.5–250 K and at 77 K, respectively. The experimental values of C p and v obtained in this study and the phonon thermal conductivity previously measured in the temperature range 5–300 K are used to calculate the phonon mean free path l for this compound. The temperature dependence of the phonon mean free path l thus determined is characteristic of classical amorphous materials.
