Abstract
The time dependence of chemical charge states in sources of O, MgO, and doped with has been studied by means of the Mössbauer effect. Charge states of , , , and resulting from the -capture decay of the have been detected. Delayed-coincidence measurements showed no time dependence of the relative peak intensities of these charge states. A time-dependent narrowing of the resonance lines is observed which is not ascribable to "time filtering" alone. The isomer shifts of the different valence states are discussed in terms of -electron shielding.
