Recent results of superconducting tunneling spectroscopy on epitaxial thin
films of the antiferromagnetic heavy-fermion superconductor UPd2Al3, are pr
esented. Strong-coupling effects in the tunneling density of stales are ana
lyzed within the framework of the anisotropic Eliashberg theory for a pair-
coupling mechanism based on the exchange of antiferromagnetic spin excitati
ons. The multi-sheeted Fermi surface of UPd2Al3 is taken into account. (C)
