| Abstract: | The Mössbauer spectra of the ammonium alum doped with approximately 1% of57Fe for T. 80K have been considered. The characteristics of the spectra have been reproduced by taking into account that the parameter λ of the spin Hamiltonian is different from zero and that the spin-spin interaction couples the states of each one of the Kramers doublets corresponding to Sz+1/2 and ·Sz±3/2. |
