Directional Compton profiles of a heavy fermion compound UPd$$_2$$Al$$_3$$ are measured in the basal plane of the hexagonal lattice. A remarkable change of the two-dimensional electron occupation number densities has been observed between 20 K and 100 K. Obtained results are attributed to the modification of the 5$$f$$ electronic states.
