The authors report experimental results of electrical resistivity, de Haas-van Alphen effect, specific heat and thermal expansion of UPd{sub 2}Al{sub 3}. The nominal composition is denoted by the formula of UPd{sub 2+x}Al{sub 3+y}. Samples with the composition of UPd{sub 2}Al{sub 3.03} and UPd{sub 2.02}Al{sub 3.03} reveal de Haas-van Alphen oscillations of the magnetic susceptibility. An anomaly is observed in the superconducting phase in the temperature dependence of the specific heat and thermal expansion of UPd{sub 2}Al{sub 3.03}. The relation between the sample quality and the appearance of the anomaly is discussed.
