We observed a clear $\\pi/2$-phase shift, which persists up to the Kondo temperature $T_{\\rm K}$. Above this temperature, the phase shifts by more than $\\pi/2$ at each Coulomb peak, approaching the behavior observed for the standard Coulomb blockade regime. These observations are in remarkable agreement with 2-level numerical renormalization group calculations.
