Abstract
One branch has been detected in the: dr Haas-van Alphen (dHvA) experiments in both the normal and superconducting mixed stares of URu2Si2 and UPd2Al3 with an anisotropic superconducting energy gap. The corresponding Dingle te mperatures increase and the cyclotron effective masses decrease in the mixe d states. An anisotropic energy gap with a line node has been discussed fro m the angular dependence of the dHvA amplitude in the mixed state. (C) 2000 Elsevier Science B.V. All rights reserved.
