The effects of impurity ions on the yield of valence states of tin after the internal conversion isomeric transition of 119mSn in frozen alcohol solutions was studied. The ratios of rate constants for electron scavenging by the solutes H+, Cr+2, and Cu+2 were determined. Mössbauer emission spectra showed that, as the solute concentration increased, the yield of Sn+4 increased. The calculation of the electron scavenging rate constants in terms of various models (simple competitive reactions, the kinetics involving the epithermal electron, and the electron diffusion model) showed that metal ions have a higher electron scavenging ability. It was concluded that the presolvated electron takes part in reactions with the solutes. [ABSTRACT FROM AUTHOR] |
