Abstract
In a Mössbauer source experiment the decay produces a large initial population of the excited electronic levels of the Mössbauer source atom. It is shown that this causes such excited levels to contribute more prominently in the source experiment than in the corresponding absorber experiment. These contributions can provide a particularly sensitive method for studying relaxation rates among the excited electronic levels. A detailed discussion and model calculations are given for dilute paramagnetic impurities in a metal.
