Abstract
UPd2Al3-AIO(x)-Pb Giaever-type tunneling junctions were prepared employing an in vacuo process. The high junction quality is evident by the observatio n of the well-known superconducting density of states of the Pb counter ele ctrode. For H-c2(Pb) < H << H-c2(UPd2Al3) an energy gap for UPd2Al3 along t he c-axis is well-resolved This represents the first direct observation of the superconducting density of states of a heavy-fermion-compound by spectr oscopic means.
