Abstract
The stochastic and ab initio (resolvent) methods for the calculation o f Mossbauer relaxation spectra are shortly reviewed. The relaxation ma trix based on a first order dynamical Hamiltonian is calculated and co rresponding simulations are presented. The spin-phonon interaction spe ctral bath densities are calculated in the Debye approximation for the direct one and two phonon processes. Some least squares fits are pres ented.
