The paper presents an inelastic neutron scattering study of lattice dynamics of the NaI alkali halide crystal, aimed to check the previously reported signatures of intrinsic localized modes (discrete breathers). It is shown that three unusual spectral features, previously interpreted as an evidence for thermally induced discrete breathers, are all absent in the independent experiments reported here.
