We report the first observation of the de Haas-van Alphen (dHvA) oscillations in U-based alloys U1-xThxPd3 up to x 0.5. In U0.5Th0.5Pd3, the dHvA oscillations β2 can be observed in the (1100) plane and the frequencies of the oscillations as well as their angular dependences are found to be nearly the same as those in UPd3. On the other hand, the effective mass of the β2 oscillation is found to decrease with x from 1.78m 0 of UPd3 to 1.32m0 of U0.5Th 0.5Pd3. From these observations we argue that the f electrons in UPd3 are nearly localized and the interactions between the f electrons and the conduction electrons are weak.
