(Ce_1-xLa_x)Cu₅In alloys have been investigated by X-ray diffraction, specific heat, electrical transport and magnetic susceptibility measurements. Resistivity \rho (T) measurements enabled the extraction of the Kondo temperature T_K(x) for the different alloys. The monotonic decrease of T_K with increase in x has been interpreted in terms of the compressible Kondo model giving |JN(E_F)| = 0.063 \pm 0.005 (J is the strength of the on-site Kondo interaction and N(E_F) the density of states at the Fermi level). Magnetoresistivity measurements interpreted within the single-ion Bethe ansatz description corroborate the magnitude of T_K found in the \rho (T) measurements.
