摘要：

The temperature dependencies of the specific heat and the anisotropic magnetic susceptibility of the heavy-fermion superconductor UPd2Al3 show distinct anomalies which can be described by a crystalline electric field (CEF) model for Uranium with hexagonal site symmetry. We find that a CEF-level scheme for the H-3(4) multiplet (5f2 configuration) implying two low lying singlets surprisingly well fits the experimental results.
