| Abstract: | The spectra of γ-quanta resonantly scattered on the nuclei57Fe contained in the goethite FeOOH microparticles reveal the presence of energetically shifted (satellite) component that arises due to the repopulation of hf sublevels during the lifetime of excited nuclear state. This observation confirms the hypothesis of relaxation behaviour of magnetic moments in microcrystalline goethite. |
