Cubic structure calculations for the temperature dependence study of the recoilless fraction and the Mössbauer energy shift of Kr 83m −9,3 keV transition are made using the quasiharmonic rigid‐atom model of the Kr‐lattice vibrations which includes the fourth nearest neighbour central force interactions. The results are compared with the experiment and the Debye model of the phonon spectra. The possibility of the low frequency Kr‐spectra not being Debye‐like is considered and the effect of the lattice anharmonicity is negligible. The characteristic temperature θ M (0 °K) of the solid Kr is found to be 25 °K which is in agreement with the experiments.
