MOSSBAUER STUDIES OF DIVALENT AND TRIVALENT FE57 IN COSO4 AND COSO4.7H2O,
Abstract
Results are reported of a Mossbauer study of Co57(Fe57) in CoSO4 as a function of temperature at atmospheric pressure and as a function of pressure at room temperature. In addition to the expected divalent Fe57 component, a trivalent component was also observed, the relative intensity of which decreases with increasing temperature or pressure. The isomer shifts of both charge states also decrease with increasing temperature or pressure. The behavior of the large quadrupole splittings observed in each charge state is analyzed using the crystal field approximation. Similar results were also found in a temperature study of CoSO4.7H2O at atmospheric pressure. The relative intensity of the trivalent Fe57 component is considerably greater in the hydrate and also decreases with increasing temperature. (Author)
