The symmetry analysis of magnetic structures of the Er{sub 5}Si{sub 3} compound, possible at temperatures of 20 and 25 K, has been performed to interpret the experimental elastic neutron scattering data obtained at these temperatures. It was shown that the smallest dispersion factor R{sub m} at these temperatures corresponds to the modulated magnetic structure in which the magnetic moments of Er atoms are directed along the a{sub 3} axis of the unit cell and form an antiferromagnetic longitudinal spin wave characterized by the wave vector k = {mu}b{sub 3}, where {mu} is approximately 0.264 and 0.274 at 20 and 25 K, respectively. The analysis of the temperature behavior of the magnetic reflection intensities demonstrated that the Er{sub 5}Si{sub 3} compound is paramagnetic at 30 K.
