(Phys. Rev. Lett. 112, 071101 (2014)) on a spatial distribution of ultracold neutrons in the gravitational field of the Earth above a mirror, projected onto a pixelated detector by scattering by a cylindrical mirror. We calculate a theoretical spatial distribution of a probability density of quantum gravitational states of ultracold neutrons and analyse a spatial distribution of quantum gravitational states in term of the Wigner function. We cannot confirm that the experimental data by Ichikawa et al. (Phys. Rev.
