Zusammenfassung:
We have studied the effect of doping on the superconducting transition
temperature T-c and on the residual resistivity rho(0) of the
heavy-fermion superconductor UPd2Al3. We have found a general
correlation between the increase of rho(0) and the decrease of T-c which
seems to be independent of the type of dopant. We interprete this
correlation as a further evidence for a large anisotropy of the
superconducting order parameter.
