  We present measurements of the phase coherence time \tauphi in quasi
one-dimensional Au/Fe Kondo wires and compare the temperature dependence of
\tauphi with a recent theory of inelastic scattering from magnetic impurities
(Phys. Rev. Lett. 93, 107204 (2004)). A very good agreement is obtained for
temperatures down to 0.2 $T_K$. Below the Kondo temperature $T_K$, the inverse
of the phase coherence time varies linearly with temperature over almost one
decade in temperature.
