Abstract. We investigate expansions according to the eigenfunctions of the Dirac differential operator, describing the motion of a particle in quantum mechanics. We get an upper estimate for the square sum of eigenfunctions and show that the expansions have convergence properties similar to those of classical Fourier series.
