By means of field theory methods, the intensity of the Mossbauer line was calculated, taking into account anharmonism in lattice oscillations. The absence of local oscillation in the crystal is assumed. On expansion of the potential energy of the lattice atoms into a series, the terms of the third and fourth powers were taken into consideration in respect to displacement of atoms from the lattice points. For the case of temperatures higher than the Debye temperature the resulting corrections to the Mossbauer factor are proportional to the second and third powers with respect to the crystal temperature.
