摘要：
To fix unstable states of pentavalent iron and cobalt, a matrix containing (according to the preparation conditions) potassium manganates (V) was simultaneously doped with iron and radioactive cobalt. The absorption and emission spectra of this matrix, with allowance for the reversal of the source and absorber functions, are similar, which is indicative of the identity of the oxidation states (IV, V, and VI) of iron and cobalt in it. Stabilization of 57 Fe and 57Co in the β-MnO2 matrix is also investigated by Mössbauer absorption and emission spectroscopy. © Allerton Press, Inc. 2007.
