 Abstract: An interface between a heavy-fermion compound and a simple metal should be highly reflecting for ballistic electrons. Since the ratio of Fermi velocities from both sides of the interface is of order 100, the transmission probability should be of order 1% only. We present point-contact experiments on CeCu 2Ge 2 and CeCu 2Si 2 revealing almost total reflection of ballistic electrons. From the measured reflection coefficient we estimated the Fermi velocities of CeCu 2Ge 2 (10 km/s) and CeCu 2Si 2 (1.5 km/s).
