[en] Reinterpretation of the neutron diffraction study of 2H-TaSe₂ by Moncton, Axe and DiSalvo (Phys. Rev. B. 16, 801 (1977)) shows ambiquity in the sense of the displacements proposed for the commensurate superlattice structure. This ambiquity is analysed using electrostatic and short-range energy calculations of the phase dependence of the energy of the periodic structural distortion wave. A new structural model for the incommensurate superlattice structure for Tsub(c) <= T <= T₀ arising from the analysis is proposed. (U.K.)
